Hanno is our man for this; as I understand it the 17pdr tank gun is not a "simple" fit of the barrel tube but some substantial mods were done to shoe-horn the thing in, isn't the whole breech assembly rotated 90 degrees? Also I think the source of all VC Fireflies and their guns was GB since the Americans were never interested in the 17pdr so the modified gun was fitted to a standard M4A4, as delivered, over here.

I'm not an artillery guy, but do know the 17-pdr gun fitted to Sherman tanks and M10 SP Guns differed quite a lot from the towed guns. The former were the Mark IV and V, and apart from having a horizontal sliding breech (vs. vertical on the latter), they had an entirely different cradle as well.
