The rear handguard is correct for a Mk1* the early single clip type have the two rivets going across the the guard, the later double clip hand guard have the rivets in-line with the barrel.
This photo shows a early Mk1 SMLE hand guard, the lefthand rivet can be seen, the rh rivet out of sight on otherside of the guard.
The bolt looks to be from a earlier1904 EFD Mk1 SMLE.
S/N from my 1904 Mk1 SMLE made by Enfield.
