Last Christmas I gave my brother a nice CZ82 from my collection (I still have 2 others of course). He returned the favor unexpectedly this year and gave me a 1946 GRI SMLE (No.1 MkIII).
The rifle is all matching and in great overall condition but the firing pin/striker is broken so I just went ahead and ordered one from Numrich. I will give a range report when I get the old war horse up and running. It looks good in the safe beside my Maltby No.4 Mk1 Lee Enfield.
FYI: Military rifles manufactured at Ishapore pre-1948 are stamped "GRI" on the buttsocket, referring to George Rex, Imperator (i.e. King George VI, last Emperor of India), whilst military rifles manufactured post-1948 are stamped "RFI", which stands for Rifle Factory, Ishapore.
