Antique & Vintage Surveying Transits & Related Surveyor
Keuffel & Esser / K & E Transits Architect, Engineer,
& E / Keuffel & Esser # 5081 1/2 Engineers Mining Transit w/ Aux Scope
/ Tripod & Attachments in Original Box This
is a very nice condition Engineer's Mining Transit. It is in near mint
original condition. The black crinkle finish is 95% or better and near
pristine noting just a few minor scuffs. It looks to have seen little
use. All motions operate smoothly. The silvered compass face is
flawless, and the 3 1/2" Gold compass needle swings north. Cross hairs
are present in both scopes. 1 white plastic vernier scale cover is missing.
NO other apologies. The nice collapsible leg tripod is included as well.
The serial # 124,320 is found on the box, the
horizontal plate of the instrument and is on the second scope as well. That dates this
mining transit from 1952
according to the charts available at
K & E marked loupe, plumb bob, oiler and more are all present. Note how the
plumb bob comes apart and is made to hold a second tip. An unusual feature that
is not seen very often.
Mining transits were developed for use in mines or places where the user
would need to shoot a line where the plate would be in the way. The
scope could be mounted on either the top over the main scope, or on the
outboard side. The counterweight is also present.
This graphic, rare & desirable surveying instrument will
display very nicely in a mining related collection or a number of other settings.
& E / Keuffel & Esser c. 1919 # 5074 Engineers Mountain & Mining
Transit This model and style transit with its
unusual 3 screw leveling base is very rare. In catalogs it gets an
asterisk with explanation that it is only available through special order. K & E called this style of
transit off as "Extra Fine". The serial # is 38611 dating it from 1920
or so. The tag on the door says the needle is calibrated for Buenos
Aries Argentina. There is a tag on the box that also indicates it came
from South America. Note that it has 2 auxiliary magnifiers to allow
for a more precise reading of the extra fine scales on the different
All motions and thumbscrews operate smoothly. The silvered compass
face is near flawless, and the 3 3/4" compass needle swings north. The black
oxidized finish is mostly fine. All three level bubbles are good and
appear to be original. The optics are clear and good.
There are a few
minor apologies. The door on the box has been remounted on the
opposite side of the opening. Not sure why and no apparent reason. There is one vertical and 2 horizontal crosshairs. One
crosshair above the center horizontal crosshair is broken or unattached.
Also, the protective outer cover or guard for the vertical circle / vernier scale is
broken. I see no damage to the wheel itself. Finally, there is a
small dent on the end of the scope as pictured.
is complete with its rare 3 point tripod. (last pic) Please look at all the pics to see the
condition and features. This rare & desirable surveying instrument will
be a highlight of the well rounded surveying instrument collection and will
display very nicely in any number of settings.
W. & L. E. Gurley Transits Architect, Engineer,
W. & L. E. Gurley #30 Light Mountain Transit Equipped w/ Burt Solar Attachment
& Auxiliary Side Mount Mining Scope This
Gurley Light Mountain Transit is set up to be used as both a Solar and Mining transit. It is in
nice used condition with the instrument and solar showing more wear than the
aux. mining scope which looks to have seen little use at all.
is no serial # dating it from prior to 1908. It is dated 1889 under the
plate. It also has the makers initials and other info there. (see
pics). The original
purchaser ordered bells and whistles for this transit that are rarely seen
on one transit and make it a very rare and unusual instrument.
In addition to the Burt Solar Attachment & #161 Auxiliary Mining Scope this
transit is also equipped with a 4" half circle vernier scale. The compass needle is 4" and operates properly.
The silvered face of the compass is nice. All level vials are full. The opaque sun shields
The auxiliary mining scope
attaches using the large knurled thumbscrew on one side. On the
opposite side the scope axle is threaded to accept a solid brass counterweight. The Burt solar attachment is
marked Gurley. The optics are good and the crosshairs in the main scope are 3
horizontal and one vertical. The crosshairs in the mining scope are a
The extendable leg tripod looks good with a repair to one clamp.
This unusual form Gurley transit
is a rare variation. This unusual instrument will display very nicely and
be the highlight of any instrument collection related to surveying, mining
or engineering. An unusual and super piece in nice overall condition. Recommended!!
W. & L. E.
Pre 1880 Gurley Surveying Transit This
large Gurley Surveyor's Transit is in nice overall condition.
There is no serial # dating it from prior to 1908. The standards are a
straight leg A further dating it prior to 1880. The rear eyepiece for
the crosshairs focus has to be held or the gear skips when focusing the
crosshairs. The optics are good. The scope is 11".
The box is correct but only has Elliot markings.
This early Gurley instrument will display very nicely in any instrument

G. W. Wilson Concord New Hampshire c. 1877 Transit
This unusual Engineer size Surveying transit is in
very nice condition. Smarts book has a short Bio on G. W. Wilson, an
early New England maker, but scant other info comes up with Google searches.
He is not in the Smithsonian 's list of makers, nor listed in the Compass
Note the very unusual pillar style round standards. They
have a great look and are a near unique feature for transits. All the bubbles
are good. Compass points north and the compass face is nicely engraved. Nice even
patina. Also included is the correct and proper taper leg tripod (not
pictured). You must view the pics to see how nice and different this
instrument is from the typical instruments from this era. The compass
is clearly marked with the maker name and location as well as the 1877 date. A nice piece
that will fi into many different collections.
& Lomb Solar Transit Solar
transits are a an unusual form of surveying transit. They were introduced or developed because of
issues using compasses that could be thrown off by mineral deposits
where they were being used. The basic
idea is to allow the user to find his location using the horizon and sun,
much as mariners use a sextant to find their location out on the open
seas with no other reference points.
Bausch & Lomb are most famous for their line of binoculars
and other optics but ventured in to the surveying instrument field after George N. Saegmuller joined the company in 1905.
This solar transit has the logo the company adopted after 1907 and dates
from right around there. They stopped making things for the general
public during WWI so they were not in the surveying instrument business for
long. There is a nice history on the company at the
The transit is in overall very nice condition.
All level bubbles are good, and motions are smooth. The transit optics are good.
A nice instrument by a maker seldom seen on the market.
/ Kassel Mining Suspension Theodolite in Box
This unusual instrument is NOS never been used. It appears it was sold
through K & E and dates from the 70's. There is a translated set of
instructions for use and a K & E bulletin announcing their carrying the
product is included. Basically it
is a theodolite designed to be hung upside down from preset points installed
in mines or tunnels.
I found another in a collection with a good
I did not do a good job of showing the knuckle joint like attachment on the
bottom that one would use to mount it from the ceiling of the mine or
tunnel. Different, Unusual, and Very Nice!!
Young / Maker Philadelphia TransitA
very early and nice example of William Young's work. Young is credited
with producing the first surveying instruments known as transits in the 1830s.
The serial # of this transit is 3859. The Smithsonian has a very
similar instrument in their collection with a serial # in the three
thousands that they date as being from the 1850s.
Solar & Mining Attachments for Architects, Engineers, & Surveyor's Transits & Related Surveying
& Berger's Pearson Patent
Solar Attachment The Buff & Berger
partnership first appeared in the 1870's and was dissolved in 1898 when both
principals opened firms under their own names with the addition of other
family members. Hence the later instrument maker names Berger & Sons, and Buff & Buff.
That would date this rare Buff & Berger solar attachment as pre 1898.
was first granted the patent for this telescopic solar attachment in 1875, and Buff & Berger offered an improved
version after 1878. Also note the handwritten instructions that are glued
into the top of the box. Faded but legible.
Solar attachments were developed for use in the field to facilitate finding
ones location using the sun and horizon much as seafarers would do with
sextants or octants. Their use was made necessary when there was a
danger of ore deposits affecting the accuracy of a magnetic compass. Each
surveying instrument maker developed or adapted one or more different
designs for use on their instruments. Other patented versions of solar
named after the inventor such as Burt, Smith, Saegmuller, and others.
A nice example of a rare piece that will make an otherwise standard looking
transit into a rare and desirable solar instrument that will display well.
