In its Original leatherette pouch..
The Gray Pocket Arithmometer.

A fascinating Engineering artifact- made to aid in figuring in the field.

Made in the USA... c. 1950.
The Morse Chain Company provided the working guts to the device.
And note:
Tasco purchased the patent and took over manufacturing after the mid-50's- so this predates that deal.

This is one of the first adding machine / calculator: and certainly the most portable.

A new fangled tool !

How to use this machine:
A pointy stylus is used to depress (poke) the numbered holes.
Add, subtract and multiply.
The shield is for subtraction.
The pull out level on the top is pulled out to clear the board.

and - from there you're on your own....
Directions are available online.

Construct:
heavy duty Steel - made to function in the field.
The case is in very good shape.
The stylus is missing.... but a pencil or other point object can be used.

measures:
5 3/8" x 3 1/8"

Condition:
Working?
I'm going to see if my Dad can figure out how to use this.
Til then- ...

For your Engineering friend... a nifty tool from long ago.
