early M1 rifle stock rebuild

[RCS]

This SA SPG stock was from the early 1940 time period when the P proof stamp was changed from the non serified P to the common WW2 serified P poof stamp in a circle. The drawing number was also discontinued too. The second P proof stamp is the non serified type used on
rebuilds. Note the toe of the stock with the small gap between the wood and the buttplate, later buttplate conversions were improved. Besides the additional P proof their is an absence of any rebuild stamps, only the faint SA SPG cartouche remains.

You Sir have some nice stuff, and some outstanding tech info, thanks!

They started to take more time on the rebuilds with the conversion to the trapdoor buttplate.
Here is a SA SPG stock with the large hole on top and the small bottom hole, They bored out the bottom hole and put a wooden sleeve in the top hole, that way both holes were the same diameter as on the new production stocks. This stock still has the drawing number too.
Also the rear was machined like a production stock for the new trapdoor buttplateAttachment 41302

robert, what is the importance of or lack of, the gap at the toe?
is this what is termed the [birdsbeek] ?---charles

The early trapless buttplate was a slightly different profile. There's pics around here if one looks...

Attachment 41361The no-trap or solid checkered buttplate and the buttplate with the hinged cap or as collectors call it "trapdoor buttplate" use two different stock profiles at the buttplate area. The no-trap buttplate curves forward at the toe while the trapdoor buttplate is in a straight verticle line.
These buttplates will not interchange without alteration to the wood. Photos show an early 1941 Winchester stock with the no-trap buttplate and two SA stocks modified for the trapdoor buttplates

Good illustrations. In addition to the shape of the toe, the side flange of the trap door plate is taller, requiring the step on the stock to be recut deeper, You can often see the line of the original shallow step in the side wall.

Yes that would be the Bird Beak which is a phrase I coined years ago as it reminded me of my birds top beak. Rick B

It's also a carpenter's term for the small wedge cut in a roof rafter where it meets the wall.
