I hand delivered a request for a sales record to Wayne Gagner at the Tulsa Show last November. It seems that I had t he letter back in a couple of weeks. I think he is a one man research operation and the amount of work he has to do may determine the time it takes to return the letter to you. What is the finish and stock type on #12155? Your serial number 1922M1is the first I have seen that had the code P after the model number. On the M2 Rifles the code P means parkerized finish so I assumed the P on a 1922M1 meant the same.
