Lookin' for a 1919A4 back plate of the "frame" type that accepts the wooden 2-piece grips, later plastic grip panels, and WWII ALUMINUM GRIPS. Would also buy WWII aluminum grips, but only with back plate (as the grips are still found on bmgparts.com now). If anyone has one of these back plates that takes the grip panels and is NOT the later solid cast deal, I'm interested. Will be fitting it to an Allied Armament 1919A4 semi auto to better replicate look of a WWII 1919A4. Thanks!
