K
& E 68-1749 (4096) 20" Desk Top Slide Rule w/ Hard Case
The 68-1749
desk top slide rule was offered for use in offices or most any desktop, and was equipped with
feet to hold it on an angle in front of the user. Prior to 1962 it
was numbered (4096). K & E also offered this rule without the hard
case and cast iron feet. This variant in the hard case is found much less often
than the typical model and they were made for only a few years after the
model change to 68-1749 and when K & E finally got out of the slide rule
making business after the introduction of electronic hand- held's. This particular rule is factory engraved with the name Elton W. Reither. Elton was the area manager for K & E in Puerto Rico and the Caribbean during this time period and this was a presentation slide rule given to him either upon promotion or retirement. This rule was consigned here by his family and has been with them since that time.
The condition is like new. There is no damage to the rule or box. Note the condition of the finish on the mahogany in the views from the back. The paper conversion chart there is flawless as well. The pads on the cast iron feet show no wear either. A super piece of calculation history in super condition.

K & E / Keuffel & Esser Thatcher #4012 Slide Rule / Calculator This is a nice but well used Thatcher's calculator. The famous Thacher calculator with its near unique sliding drum design has scales totaling over 30' long. The inventors name is really Thacher, but it was mis-spelled on almost all versions. hence the use of two different spellings.
Thatcher slide rules were first patented in England in 1881 and were an immediate success with the scientific and engineering communities. K & E bought the rights to produce them, and initially Stanley of England produced them in England before K & E moved production to the states near the turn of the century. .
The serial # on this instrument is XXXX . The overall condition of the rule itself is good with no chips or damage to the scales to speak of. There are just a few very small brown spots, most no larger than pin heads on the outer scales. The scales are a light mellow tan / yellow that is normal. The inner scales on the drum are very nice as well with no damage or lifting. The instructions on the base are worn but present. The mahogany box is nice and has its original finish. There are no names carved into the box or base of the calculator itself..
A nice example of this rare and interesting calculating slide rule.

French
Circular Calculator / Slide Rule
This unusual
French sliderule dates from just after the turn of the century. I could turn
up little information on it with Google searches. I assume the name is Le
Calculateur as seen in the right corner. The tag in the bottom right gives
a company name that again did not show up in a Google search. That is where
the serial # is. It has a very low serial # of 546. The calculator
is mounted to a wooden frame, and the background is a plastic material that is oftentimes
called ivorine. It was a material that did not have good movement characteristics,
and in situations like this oftentimes cracked or chipped where attached.
The face of the slide rule is nice and was protected by a clear plastic window that
is wavy, but OK. The arm which you read the calculations from is articulated
such that it can follow the spiral lines on the face thus enhancing or magnifying
its capabilities. An interesting calculator. Click for Pic Click for Pic Click for Pic Click for Pic

Fowler
Long Scale Slide Rule / Calculator
Fowler is a well known English name in circular
sliderules / calculators. They made a variety of different models and size
calculators including many circular versions like this one. Some were designed
for architects, or engineers, and others were made for the textile trades.
Larger ones are referred to as Magnums, and this 2 3/4" model is referred to as
the pocket size. This Long Scale Fowler calculator is in super
like new condition with its outer hard shell marked case. The original instructions
are included as well. There is a plaque inside the case that gives the location
as Manchester England. There is a serial number under the glass on one side, but
there is no specific model designation other than the long scale that I can see.

Stanley
Fuller / London England / Spiral Calculator / Sliderule This
Stanley Fullers Spiral Calculator / Slide rule is in nice condition. This is
an example of a calculator that is getting harder and harder
to find. They were first introduced in the 1880's. At first
they were made and offered by Stanley of London a well known firm that also
made the famous Thatcher calculator, and other surveying or engineering
related instruments. Later on K & E
bought the rights and offered them until the end of production in the early 70's.The serial #'s numbers on the brass scale are 6900 -37. I believe that indicates it was made in 1937. It has the brass external mount feature so that the slide rule can mount for use on the outside of the box, but the mounting bracket itself is missing. The box is pretty nice, and is mahogany. It has a finger joint design in the corners. It has a nice green Stanley label inside the top. It is in overall good condition noting the remnants of another label or sticker on the outside top.
The inner scales are very nice. It has the typical scales and charts found on these type one model calculators, and the outer scale has the typical light brown tint to it. The scales, both in and out are in very nice condition noting just a few minor dings. The short pointer is marked Fuller Calculator, and Made in England. The long cursor in addition to having the date and serial number is graduated along one edge. A nice piece in outstanding condition.

Stanley
Type 2 Fuller Spiral Calculator / Sliderule This is
a nice condition example of a very hard to find variation of a Fuller /
Stanley slide rule calculator. The numbers on the brass scale are 5836 -27.
I believe that would date it from 1927. The finger joint mahogany wooden box has a
Stanley paper label in the top, as well as a tag, from I assume, the factory
it was being used in. I am not sure what the name of that company was,
but the tag says it is from the aircraft division and 54 over 14690.
The box is OK noting one latch is missing, and there are some paint spots on
the top. It does have the mounting bracket on the end of the box, and
the proper bracket to mount this calculator is in the box. As for the rule itself, the scales are pretty nice with just a few small dings here and the typical yellowing the paper scales develop. There is a hairline crack in the top wooden donut as can be seen in one of the pics. It is just a line in the wood, there is no damage, movement, or looseness. There is also some minor staining, dirt and chipping of the paper at the top and bottom of the outer cylinder. The short pointer is marked Fuller Calculator with Scales of Sines & Logs Made in England. This is what makes this model so unusual. One can see the difference immediately on the inner scale as there are none of the typical tables or equations usually seen. This inner scale is made up of 2 sets of scales from top to bottom. A rare piece in nice condition.

K & E rule is from near the end of the production period for slide rules. The
world was going electronic, and K & E changing its model #'s was not going
to help.
The rule is a #1210, the box says it is for a 1220 and the manual for
another rule. I believe it is all correct and that K & E was just
moving product out. The case is fine and marked w/ the previous owners name

Gestation
& Farming Circular Calculator This is an interesting circular
calculator. I am not sure of the story behind these, but you can find them
with various company names and promotions for different farming products.
They were a well made product, and most have held up well over the years.
This example is in very nice condition with one scratch that can be seen in the
pics. The condition can also be explained by the fact that a calculator for the gestation period for different animals for a working farmer is similar to the saying, "if you need to ask you probably do not need to know". I could find nothing under the planting info that warned about, or took into consideration, what the weather was that week, or had been, when computing out when to plant, and how long it would take. Different & Very Nice!!
