Here are a lot of comparison photos of the prototype sheet metal parts (TG, FP and follower) on SN S319. While not perfect, its the first one of these to surface. Mike has
some recollection of seeing another 'S' prefix but so far no luck in digging any data on that one. The best we can come up with is that a run of these rifles with the new sheet metal
components were assembled later in 1942 (stock is dated 33rd week of 1942).
I have some sheet engineering drawings that I will post up later. Mauser orgininally designed these components in 1942 with the initial production and use of sheet metal components showing up by early summer of 1943 (May - June, d to e blocks).
The comparison sheet metal parts are standard production parts from a 'd' block byf44.
The one detail photo of the front well of theTG shows the WR Mauser inspection stamp. Also note that the intial design of the sheet metal TG attempted to copy the build up on the front face of the guard ring (as found on milled guards). It was eliminated on the production model.
Also a big thanks to Eric for finding this on GB in the first place.
Added note: The metal finish on all the stamped parts is unusual in that it appears to have a granular appearance, almost 'bead blasted'. Another test run at finishing the sheet metal I suppose. A close examination of the photos will bear this out.
