Repro Comptometer Adding Machine Instruction Manual User Antique Controlled Key

Description

Reproduction Instruction Manual for the Comptometer Adding & Calculating Machine (like the example in the inset; actual adding machine not included).
This is a page-for-page copy of an original instruction manual from my personal collection. It looks vintage and authentic so you could display it with your typewriter without feeling like it looks too new.
24 pages including covers.
This item will be packed in a waterproof sheet protector, in case it rains, within a stiff cardboard mailer.
