Hi all, new guy here. Love this forum. I just recently picked up a SA 1903. Here are the points of interest, 649425 serial number, 4-17 SA barrel, small s at tip of stock, one screw FG stock which is marked ELH on the side. This is an early high wall stock. Proof P is almost gone. Bolt safety lug is marked C13. This rifle is all blued. I was wondering about the stock though. Isn't this way to early for the time period?
