Yes it does... an X and a D with something poorly stamped in between... could be an L... could be an E so it could be XLD or XED

Whatever the stamp is, it is most likely a date of manufacture rather than a repair code.

Finished December 1935?

Most probably...

Made in Meriden by former Parker Bros. employees under Remington Arms ownership.

I wonder what the letter says?

Definitely cyanide.

OK I was able to blow the photo up and it appears the numbers and letters are X10D, or X14D, The stock has the serial number and grade stamped in the wood I removed the trigger guard before I bought it 7 years ago, I do have a letter, by Kirby, GHE 32" 1-1/2 frame 12 gauge, like I say I am away from home till Friday so I cannot take photo of letter till then, Gary

Gary, I looked up the letter for your gun. We only have the stock book and basically it confirms the gun as you stated but does not say anything about the butt stock. I can post a copy of the letter or send it to you as an attachment.

I took some shots of my stock last night. I think I attached the pix correctly. We shall see.

Hi Mr. Spin Drift,

Your stock is definitely not made by Parker Bros. and to be honest, it doesn't have any of the identifiable Remington features.

It is however, a beautiful piece of walnut!!
