Welcome back A square 10 ....
A beautiful piece and certainly a rarity.
I think there were only about 20,000 of these rifles made between 1922-1924.
I think while you were away we added one of these to the England - Milsurp Knowledge Library (click here)
Yours is a 1923, whereas the one in the library is a 1924 ShtLE (Short Lee-Enfield) No.1 MkV Rifle (Mfg by RSAF Enfield) ........... click here.
