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.
