I have Iron mounted Enfield stock. The lock is marked Charles Lancaster, The stock has a hole near the butt that has a wood plug in place. The stock is cut at the back of the lower barrel band. I also have Iron barrel bands. could this be a P-58 or later sergeants rifle?11500115011150211503115041150511506
