Here is something that might or might not be of interest but maybe someone can shed some light on it.

I cleaned up my Maynard project stock yesterday. It looked solid but really grubby so I sprayed it down with oven cleaner and scrubbed the heck out of it with steel wool; that took what finish was left and the crud off and the lye left the wood with a nice dark color. I then steamed the dents out and gave it a light sanding with 280 and then more steel wool, followed with a couple coats of oil. Came out great.
On the right side, stamped in the wood, just back of the receiver is the letter E and again on the right side just in front of the but plate the same E; on the bottom of the stock just behind the lower tang are the letters F.F.P. The stock appears original to the receiver as everything has the same serial number. I also believe  this receiver was never military. What are these letters, inspector  marks?
