1st Model Wooden Case ShoeBox Comptometer Adder / Calculator1st Model Wooden Case "ShoeBox" Comptometer Adder / Calculator   The serial # on this 1st model Comptometer is 2190.  It is stamped into the metal cover over the counter area near the middle.   These early wooden case comptometers were offered beginning in 1887 and were sold through 1903.  During that period a little over 6,000 were produced.  After that the machine was cased in a metal housing.  The basic idea remained pretty much the same while going through a number of minor cosmetic changes over the years. 

There is a very informative and worthwhile site that details the history, design, operation, and other info about these machines on the internet.  It can be found at www2.cruzio.com .  This 1st Model Comptometer is listed there along with the other known wood case examples that have turned up.  Known wood case models number under 100 according to this chart.  This example came from at descendant of the original inventor / maker whose name was Felt.

All of the main keys seem to operate as they should.  There are none that are stuck. By manipulating the key strokes I can get it to zero out, but the black knob on the side which is supposed to zero it does not turn or operate.  The wooden return lever moves but does not seem to do anything.    In general when pushing the main keys it seems to carry over pretty good, except for the last column which seems to skip or overcount at times.  The main parts of the case are in Mahogany and the base appears to be a softwood like pine. The outer case is in very nice condition and looks to be original finish.  The bottom cover door is missing.   A new panel could easily be fabricated if wanted.   These wooden case comptometers only appear on the market occasionally.  Some have been known to sell in the $4000 - $6000 range, and we have this one priced to reflect the minor operational  issues mentioned above.  A rare piece that will be a welcome addition to the advanced collection of early American calculation devices

Comptometer Adder / Calculator Comptometer Adder / Calculator   The Comptometer Adder / Calculator is one of the most commonly seen and well know of all calculators.  The first models were housed in a wooden case and are quite hard to find, but these later models in tan / brown metal cases are quite common and abound.  This one is in pretty nice cosmetic condition, but is being offered as just a shelf / display piece.  They make for a nice display and speak to how far along we have come since these were phased out by more advanced adders and calculators.

Base 5 Adder / Calculator Adder / Calculator   Here is a different one.  I flunked non Euclidian geometry, and did not do much better when they had tried to explain base 5 math before that but that is what this seem to be.  It looks like it can carry numbers from one column to the next, and none makes any sense to me. It says it was made in Japan, perhaps it is for counting Yen.    Different.

Curta Type 1 CalculatorCurta Type 1 Calculator  This Type 1 Curta calculator is serial number is 51545.   The Curta calculator was invented by Carl Herzstark while imprisoned in a German concentration camp during World War II. On the bottom of the calculator is says "System Curt Herzstark, Made in Liechtenstein, by Contina AG Mauren, Type 1 No 51545.   Case dimensions are approximately 4 5/8" tall by 2 1/4" diameter. Inside of case has both foam pads to protect the device during transport. 

This interesting design calculator was the top of the line and immensely popular before the advent of the electronic handheld calculator.   Their introduction and development made this technology obsolete in the early 70's.  It took a few more years for them to be recognized as the collectible pieces they are today in scheme of things. 

This example is in good condition and operates flawlessly.   The previous owner was a surveyor and the body is marked 6 over 3-4798 with an electric pen in the side as shown in the Pics below.  Otherwise the body is very nice and shows no wear or tear. 

The metal case does show a lot of scuff marks with the black anodize finish rubbed off the high points.  Again the operation is flawless though, and this one could be easily put back into service at rally events or in the field with a surveyor.
