Could be, but there is an R on the right side of the trigger, the trigger guard is not pinned. There is 9974 stamped on the right side of the stock, which is a replacement anyway. The finish does not seem indicative of a Greek lend lease. The rifling is really very good. Is Greek return a good or bad thing. I am new at this. It started with an Enfield and now an M1 and the 03A3.
The 80 year old got this Greek rifle 25 years ago. CMP only got them from Greece about 10 years ago.
