Staghond MG mounting issues

[daninnm]

This is a gun issue for the Staghound restoration we are doing. The No. 523 Stag was apparently equipped with a coax gun that was NOT A STANDARD M1919!? The rear mount attachment to the M24 37mm gun mount that is supposed to hold the mount pin for the M1919 does not fit a M1919---that is the two “ears” of the pin are not in the right place to work with a M1919.
We suspect that the Australians used some different MG as their coax gun (a Breda???) We don’t know and cannot find NY reference or pictures. Anyway, the casting that is on right side of the M24 is not correct and I have been told that the Grant Tank mount for its 37mm gun has the correct bolt-on attachment part that works with the M1919 mount pin.
QUESTION: anyone have that part that would “RENT IT” so I can have one molded from wax and then cast in steel or aluminum???? A set of accurate dimensional photos might also work since I can make my own ‘lost wax’ piece to send to a caster.
Thanks! Comments?
