This is a nice example of a Fowler's
Jubilee Magnum Extra Long Scale calculator.
Designed in 1948 by Harold Fowler to mark the 50th
anniversary of the founding of the firm by his father William
Henry Fowler in 1898.
This was the largest circular calculator made by Fowler's measuring 12cm
in diameter, and it has a 79" long scale extending
over ten circles.
In full working order, with a chrome backplate, the scales are very clean,
and the overall condition of the calculator and its leather case is very
good. It also comes with its original instruction book.

This particular example has come from the RAF, and the previous owners name is hand written in ink on the red feltbox lining and reads: ' P/O Wiggins. D. M. RAF'
Known also as a 'Vest pocket' model, these double sided calculators were recommended as the most comprehensive and accurate pocket calculator ever made, and this model dates to the 1930's.
It measures 2 1/2" diameter and in good working order, with nice clean scales on both faces, one side reads 'Fowlers Calculator' and the other 'Fowlers Long Scale Calculator'
The overall condition is excellent, including the nickel plated case.

Although the calculator was sold through W H Fowler’s Scientific Publishing Company it’s not clear who designed it or where it was made, but you will see from the close up photos the central steel disc has the word ‘SWISS’ engraved on it, along with “THE MECHANICAL ENGINEER” printed on the scale surface.
Fowler’s did not start producing their range of calculators until 1908, and it’s likely some of their designs were based on this first Swiss model.
A very rare calculator measuring just over 2” in diameter not including the crown & stem, it is in very good original condition. The bevelled glass cover is free from any chips or scratches, and the nickel plated case does not have any dents. The card scales are very clean and legible, and the large milled crown rotates the whole dial, with the side knob controlling the pointer needle.
Serious collectors of these items will recognise the importance of this particular calculator which is well over 100 years old and probably deserves to be in a museum for posterity.

This is a quite exceptional example of
a Fowler's Jubilee Magnum Extra Long Scale calculator.
Designed in 1948 by Harold Fowler to mark the 50th
anniversary of the founding of the firm by his father William
Henry Fowler in 1898. This particular calculator comes in a special presentation
case which suggests it was one of the first models made in 1948,
probably for promotional distribution.
This was the largest circular calculator made by Fowler's measuring 12cm
in diameter, and it has a 79" long scale extending over ten circles.
In full working order, with a black hammer finish steel backplate and
a bright nickel outer body, the condition of the calculator and its velvet
lined fitted case is near mint. Its doubtful that there are many of these
presentation sets left, let alone in such fine condition
(the photos don't do it justice!).

In excellent condition,
a fully working Fowler's Twelve Ten calculator in a superb
presentation box with 'The Fowler Calculator' printed
in gold lettering on the lid. Known as the 12-10 because it includes scales
to convert twelfths to tens, yards to metres, lbs to Kgs, inches to centimetres
etc. Introduced in 1936, this particular calculator was primarily designed
for Architects, Surveyors, Builders and Craftsmen, and is one of the more
hard to find models, particularly in such good condition with its own
special Fowlers presentation case (size 4" x 5").
Comes with a photocopied page from a Fowlers advertising brochure.
Please note the slight red hue on the black case outer is only from the flash photography, and is NOT a blemish on the case which is in excellent cosmetic condition.
