PT334 was experimentally fitted with a 75mm M4 aircraft cannon on an M2A3 gun mount. I have the manual for the weapon, but cannot find an image of the mount? Anyone familiar with this mount? I suspect is was a simple, low angle manually-driven mount, as it was lighter than the standard MK3 40mm mount fitted to PTs. I'd like to do a drawing of her in this configuration.

Thanks,
