Contex
Model   B
Maker   Carlsen Brothers
Origin   Gentoft, Denmark
Date   1960 -
Serial   605407 (shown) and 134245
 
A more modern appearance than the model A, looking like a calculator but still mechanical and still only able to add. The internal workings are similar to the earlier model A.
 
The half keyboard design allows experienced users to operate the machine very quickly, pressing two keys where necessary.
 
Designed for £sd sterling and including farthing and halfpenny keys, this model was introduced in 1960.
