I just picked up a Ishapore Lee-enield 2A. Not a 2A1. Mine was made in 1964. it has all matching number and has a GREAT and clean bore, the stock is in about perfect condition all but a crack near the butt plate. I know that the rear sight is the big differance between the two rifles. i also know that there were only about 50,000 of the 2A rifles made. My question is: Is there a differance in anything else besides the rear sight? and my other question is: Is there a differance in vaule?
