Maker Of Type III Recoilplate Marked SC

[painter777]

Trying to help out a member on the CMP who has a Type III Milled Recoilplate marked on the inner right edge SC

I'll assume since it's marked it's WWII era, since (most) parts made during that time were marked.
I've often wondered if they were made for 'extra' stocks made by Sprague&Carleton's metal supplier, but have no proof.

Any idea Gentlemen who this maker may have been ?
I currently see some of the same being offered on ebay, but the descriptions only list them as NOS.
Can you help me... help him?

I've also posted this on the CMP and The Carbine Collectors Forum... Links below:

Appreciate any help,

Charlie I would lean towards Standard Products, made by Climax Ind. Co.,. They did supply recoil plates but the codes not be confirmed either.

Charlie, My mistake, I would think it would have Standard Products on top, so strike that reply.
Best of luck, GSP

The 'C' is probably a 'G' and that's Saginaw. However, none of the prime contractors made all 60 some parts. Saginaw only made 17 of 'em. Standard Products used a plain 'S' but only made 4 of the parts including receivers. It might be Sprague & Carleton, but would not be their metal supplier. Metal suppliers just sent bar stock.
Literally hundreds of small shops all over the Eastern U.S. made parts. That alone means there's no such thing as the fabled "correct" Carbine.
