mine is built on an FTR 1918 NRF action.
New barrel, Suncorite (?) finish in 1945. Enfield said they stopped ALL work on the SMLE in 1943.
I think they are experimentals. Some people think my eyes are brown because of the BS level!
That still leaves us with a couple of rifles that don't exist.
I was told, many years ago, that Enfield was experimenting with these just after War 2. Several ideas were involved:
1. rapid finishes (Oddity: I am told that Suncorite is very durable; this stuff scrubs off easily with steel wool. Help here appreciated.)
2. recycled Ross butts (I was told 12 done.)
3. composite wood/aluminium forestocks (I was told 6 made. Quality of the casting is very impressive: NOT done in Bubba's barn.)
Test ideas were to do with (1) rapid finishing methods, (2) practicality of recycling older wood in case of future wood scarcity, (3) practicality of new materials for future production. In passing, I note with interest that the M-16 is based on a precision aluminum casting. Connection? Everything has to start somewhere.
I was told that in the middle 1960s, did not see one until 20 years later.
Mechanically, mine matches. Serial is R69111. Barrel date is definitely 1945.
