The photograph above is from an advertisement for the Comptograph (no model given) from Comptometer Ltd., in 1959[1]. It shows a machine for use with the old British non-decimal £sd currency since it has extra keys marked "10" and "11" above the other keys. The advertisement claims that the machine features "Exclusive visi-balance window, super-fast, unusually quiet, compact keyboard, concealed paper roll, adjustable legs, non-print lever, two-colour printing, and many other features".
Comptometer Ltd. in the UK. was amalgamated in 1961 with Control Systems' Sumlock Ltd. to form Sumlock Comptometer Ltd., and it is recorded that Comptograph machines were exhibited on the Sumlock Comptometer stand at the Business Efficiency Exhibition in London in October 1963[2].
John Wolff has information that these machines were actually manufactured by Walther in Germany and rebadged "Comptometer". It is actually a Walther Model P12 - see http://www.johnwolff.id.au/calculators/Walther/Walther.htm#Printing.
