Hello and congratulations bigmoose, I have an identical equipped K-22 Outdoorsman and the first four numbers in your serial number are the exact same, the one that lives here was shipped in Aug, 1937. I was thinking the stocks had been replaced but after seeing yours, I'm not sure. The stocks on the one I'm in charge of are not numbered at all! They are pre-war Magnas!
