I made a previous post about this gun but figured I'd make one and show some more pictures. I know the ramrod, nose cap, and rear band appear to be wrong for this model. Any other insight is appreciated.
If you turn the barrel bands around they will fit better. The P53 Enfield had the screw heads on the left side of the gun, and every part on it was hand fitted.
Have you found any stamps/marks in the stock, or on the breech {aside from the B'Ham proofs} ?
