SN 47039 Snap shot in time

[CCyooper]

I'm not exactly sure when this training chart was made but it was included in the large deck of training aids produced by the Army. I suspect it could have been as early as 1941. Most of the charts appear to be from the 43 time frame. Here we have SN 47039. Who knows how many modifications the rifle went through but here is how I see it. Numbered gas cylinder with seal, checkered knobs no groove cover w/out number. Short riveted follower rod with late spring. Late oprod catch, long slide bullet guide. trigger housing -1 or later, no hole trigger, -2 hammer, flat -4SA safety, plunger and housing in the white. Cannot tell much about the stock other than the ferrules and clips are grooved. I'm trying to determine if I can snap a pic to see if the bolt can be determined.... just thought I'd through this out there while waiting for round two of shoveling.

Very nice, love graphic training aids and that’s a nice early one.

Curt, the training chart rifle looks very correct except for the late operating rod spring and follower rod. Trigger housing could have had the pad modified and the later spring changed ? otherwise I believe the trigger housing should be D 28290 SA with the large pad. The op rod catch could be early or late. Looks like a no trap stock

I did some checking on data sheets on rifles in the late 40K and early 50K serial number range and found quite a few -1-SA trigger housings. Believe there is an overlap on the D 28290 SA and D 28290-1-SA trigger housings

Photos show SA 52112 with D 28290-1-SA trigger housing, SPG no trap stock with two equal size holes and keystone/comp spring (some restoration done )
