Cali201: Receiver has an adjustable sight, marked SA. I'm assuming this is a post-war replacement -- is that assumption correct?. Also has a barrel band with bayonet lug, but a push button safety, marked EW. I haven't had time to disassemble it yet, but all in all, seems to be a confusing mix of parts/features.
Any thoughts on when the barrel would have been replaced? Muzzle wear on the barrel is about a 3, so it seen considerable use.
Thanks,
Jim
