Victor
Model   500
Maker   Victor Adding Machine Company
Origin   Chicago, USA
Date   1940s, 1950s
Serial   396960
 
A manual machine for sterling currency. Has four columns of keys for pounds (the thousands column in white and the rest black), two for shillings (white), one for pence (black) plus one with 11d, 10d, ¾d, ½d and ¼d keys.
 
On the left are additional keys marked Error (top white) and Repeat (bottom red) and on the right are keys for Sub-Total (top blue) Total (top red), Subtract (lower red) and Non-add (bottom blue).
 
Subtraction works provided the result is positive, but a negative result is shown as the complement, not the actual value.
 
The total and sub-total can be printed in red if a two-colour ribbon is fitted. The fitted metal spools operate in both directions to get the best use out of the ribbon.
 
Below the keyboard is a mechanical display showing the current total.
 
This machine is very heavy but its solid design is probably why it survives in fully working condition.
 
This example shows:
Add 19/11 17/6 and 15/8
Subtotal £2/13/1
Subtract 12/9
Subtotal £2/0/4
Add 18/10 14/11 and £1/19/11½
Total £5/14/0½
