I’m new to these rifles, mine is different than what was noted above, it has a globe front sight, PH FS22( it looks like the barrel was machined to accept it) , rear T/Z 4/47 J Parker sight, there is a holder for sight inserts on the RH side of the butstock, receiver is stamped C N4 MK 1* LONG BRANCH, 1950. Sn 94L1651, no other numbers are visible, bolt has been cut and re- welded and finished (vg workmanship, not a bubba) band on the fore end has CE1967 stamped on it. It may be something pieced together by a gunsmith, it also has the finest trigger I’ve ever squeezed on an Enfield. Someday I’ll have to shoot it.
