Looking at mine - serial for 1929 and barrel stamp matching - The peep is marked 6 on the left and R on the right. First thought would be the R is for Remington, but that's just me. Is it that, or something else?

There are also no arsenal or personal marks on the stock, but the metal is green, I guess just because it evidently had the Parkerizing replaced, doesn't mean the same is indicated on the rifle? Am I correct in that thinking?
