M1 Carbine Stock Question

[painter777]

Yes, Looks like a faint Stan Pro CC. Will have to remove Recoil Plate to see marking.
Is that a Stamping on the Left Side of Stock just behind Grip?
Is that a Metal Burr under your Extractor in your Bolt picture? Inspect that and the Rails your Both of your Bolt Lugs ride on **
H in Shield rear Sight came on some S'G', depends on Serial number.... I Need to double check. Need your Serial # and if Receiver has any marking on the left side (below wood line)
Type III S'G' trigger Housing has replaced or possibly a Transferred Underwood straight Hammer. Can see it has a S'G' Trigger.
KV-S'G' Type I Swivel, made by Knape Voight (sp?)

Concerned about the rails the Bolt lugs ride on, especially where the left lug rides in. See the picture and raw metal areas.

It looks nice. I'd really degrease the action and look for Burrs on any of the guide rails. After a Deep cleaning a cotton ball will find Burrs for you.
Curious if that's a Stamp on the left of the stock.
