Calculation
Thacher's / Thatcher
Calculating Instrument Calculator / Slide Rule
15 Page Instruction Pamphlet All
original, not a reprint. I am not sure if this ever had a cover or not.
It is instructions and testimonials, 15 pages all told for an early Thacher
/ Thatcher calculator. I see no date, nor do I see a model number to
indicate if this predates K & E numbering their Thacher the 4100.
I think it is correct with 15 pages and was a supplemental, or quick guide,
as opposed to a full set of instructions. The condition is as seen.
Frayed w/ loose pages.

Curta
Calculator Type
II No. 557878 The serial # on this
Type II Curta is
557878. This
Type II Curta Calculator is in excellent condition and operates smoothly and flawlessly.
The body is very nice and shows minimal wear or tear. There are minor scuffs
on the sole. The plastic case is nice.
The Curta calculator was invented or
developed by Carl Herzstark while imprisoned in a
German concentration camp during World War II. This interesting design calculator
was the top of the line manual calculator in its day and
was immensely popular before the advent of the handheld
electronic calculator which essentially made them obsolete in the 70's.
In
todays world they are at times used in road rallies and some other applications
but are worth more as collectibles and examples of calculation history. They were made
up until about 1970 and all told about 150,00 both Type 1 & Type 2 models
were made. They are highly collectible pieces of calculation history today, and an
important example of calculation technology in the scheme of things.

Electrical
Thomas Edison's
Edison System Ampere Meter This Edison System ampere meter is a rare
and important piece of Electrical history. The condition of this large and
unusual Edison amp meter is exceptional. The scale reads up to 264 amps, off the scale, indicating this meter must have been
used with a huge dynamo or motor.
This Edison meter measures approx. 10" across
and 16" tall. The back of the case is cast iron. The etched glass face is
flawless. The previous owner made a copy of the paper scale
to cover the original scale to help preserve it. The original paper
scale is behind the copy on the face in the pics. It is in nice
condition.
The wooden case is original finish and in fine condition. The
interior workings look like new. The wooden case is stamped in two places
with Elec. Eng. Dept. L.S.J.U. which is Stanford University in Palo Alto CA.
A super nice and rare piece of American Electrical History that will display well and be a great addition to the old office,
electrical, scientific or related collection! Nice!!

R.Fuess Berlin-Steglitz Stech - Hygrometer / Long Barometer
Moisture Tester This Long Barometer
Moisture Tester is an interesting scientific device by the well known and respected German maker R. Feuss.
It is in near mint condition and includes the original instructions - in
German. It is housed in a fitted wooden box.
The collector had the
instructions translated and written out in long
hand. It seems from a light reading that this device / instrument was intended to
determine the moisture content or humidity inside things like bales of
tobacco. Tobacco is the material mentioned in the instructions, but I assume other materials or crops
that were aged and or allowed to dry out before use or processing would be
suitable candidates as well.
The long tube has a series of holes in it at the bottom that open and close during the test. I
remember buying a lb. of something one time that seemed a bit wet. So much
so that it was about un-smokeable as it was. After two nights in a
heated dry environment it lost half its weight as it dried out more. Half
its weight = half its value. I imagine buying tobacco or other similar
commodities by weight was much the same and this device was a way to keep
one from
over paying for an overly wet and heavy product.

outer box, and the Binocular Magnifier are marked Zeiss. The inside of
the box has a EB Meyrowitz label. Meyrowitz is a well known name for Microscopes and
accessories and probably marketed it. There are 3 sets of lenses each marked with a different
power, 25 being the biggest. Somehow I left out a pic of the front.
The lenses are all good. It is marked with a #1686 and Germany in
addition to the Zeiss name. It also says 62mm and DRGN on the right
side.
