So my uncle passed about a month ago and my aunt is unloading to move. She gave me 2 303 brit #4 m1 1941 (1 for sure?) sporterized? here are some picks.. one looks stalk handcut the other is cleaner newer stalk. These were my grandfathers purchased in the 50's or60's? I found 348 ammo labled 10/46 for the other old gun he gave me a couple years ago!! what do I got here fella's??
