"The Tourtel is a printing adding machine with setting levers just like the pin-wheel machines. It is equipped only for English currency. The lever on the right side of the machine is marked F (farthings), followed by D (pence), I (shilling), and finally 10 (shillings). The remaining three levers are for pounds - the machine is thus capable of adding up to £999.
The designer is John Mesny Tourtel, London. and the manufacturer is The Tourtel Adding Machine Syndicate, Ltd.. 57 Chiswell Street, London E.C. "

The locking device on the machine has been patented - it prevents the crank from being turned before it is in the correct position and also prevents the machine from being damaged by incorrect handling."

"This machine was brought onto the market by Sirius-Werk, Wilhelm Keil in Nördlingen. It is shaped like a cash register with vertically positioned calculating gears. In place of the setting windows, the calculating gears have handles with knobs by means of which data entry can be carried out manually. The machine had nine places and cost 150 marks, but it has now disappeared from the market."

"The Teetzmann machine is distinguished from other pinwheel machines largely by the fact that it has nine setting levers and control windows in front of the carriage. It is possible to operate the setting levers with the left hand only, while the right hand remains on the crank.
The machine is 20 cm long and 17 cm high. While there are only a few of these machines in Germany. a large number of them have been supplied from Manchester in England, and overseas under the name of Colts Calculator.
Manufacturer: Teetzmann and Company, G.m.b.H, Charlottenburg. Frauenhofer Strasse 18/19. In July 1915, this firm went into liquidation and the machine is no longer being manufactured."

"The Burroughs Calculator closely resembles the Comptometer described earlier. It is a calculating machine in which the keys directly operate the calculating mechanism, which is underneath the keyboard, so that neither crank nor electric drive is necessary.
The machine is only available in seven-place or thirteen-place versions; both models have an extra place in the result mechanism. There are special models available for fractions and English currency.
Manufacturer: Burroughs Adding Machine Company, Detroit."
