Callendar Abbots
Both Callendar Iron Co. Ltd, Falkirk and Abbot's Foundry Co., Falkirk supplied material for the war effort in WW1. They amalgamated in 1933 to form Callendar Abbots Iron Co. Ltd.
Callendar Abbots supplied 1,990,000 No.36 MkI between February 1940 and June 1945. From the beginning of 1943 they were one of a dozen companies selected for continuous production contracts (supplying 1,625,000 in 11 sequential batches). These figures do not include reject bodies sent to another contractor to be turned into practice and drill grenades.
Base plugs were supplied both in cast iron and mazak. CI base plugs could be rustproofed in a variety of ways, of which electroplating was one method.
Question is, is C/A (rather than plain CA) the maker's mark for Callendar Abbots? Body castings with C/A are sufficiently common to support the view that it is, and the "/" may be indicative of the Foundry having two distinct ancestors.
Anyone any other thoughts as to why C/A, or to whom else it may refer?
