[1942] "TRUCK 15 CWT. 4 X 2 AA (20 M.M.)" C.15..thanks Geoff!
This photo is of a prototype twin-Oerlikon mount that was normally fitted to ships of course. Now, the interesting bit is that these may have been all-GM of Canada production. The mountings were made by Regina Industries Limited in Regina, but the special tooling was made by the Oshawa Gun Plant. The truck I assume is a C60L, but where were the guns made? I assume Border City Industries Limited in Walker Road, Walkerville/Windsor.
Can I ask a stupid question and ask what the difference was between Oerlikons and Polstens?
