Tiff has it. but he only sell it with his t23 turret kit.
1. in history, did us army use 76mm gun on this turret? not sure about that.
2. I know even when t23 turret sherman, they took the muzzle break off becuase german will pick the 76mm gun shermn first. so they took the muzle brake off to look like regular 75mm gun sherman.
good luck. tom
