Thanks, Jim and Calfed. I did something similar with my M1, but got a little carried away and I think the photo is too busy.

Thanks, Rick. Also, the chart on the Remington Society of America web site matches ViShooter. Which, I misread. The correct date of production on the receiver should be September, 1943. A nice companion to my M1 which is from December, 1942 with a '46 barrel.
