Ajax

Ajax was a trade name for the calculators marketed by Acme Electric (Finsbury) Ltd.
There is little information available about this company though some calculators were manufactured by Advanced Telecommunications Equipment (ATE) of Woking, Engand, which was linked with Radofin, whereas the 2500 (below) was made in Hong Kong.
