Model   A
Maker   Carlsen Brothers
Origin   Gentoft, Denmark
Date   1946-1960
Serial   129373
 
Made of bakelite, the model A has a half keyboard. This example is for sterling £sd but does not have fractions (halfpennies and farthings). The half keyboard design allows experienced users to operate the machine very quickly, pressing two keys where necessary.
 
The base of the carrying case can be left under the machine to give a more stable operating environment.
 
The model A was introduced in 1946 and manufactured until 1960.
