W1537 WINCHESTER MODEL 62A; Replacement barrel in caliber 22 Short. This barrel has the P in a circle. There are marks on the barrel near the receiver probably from some gunsmith years ago. Mag tube looks like it is a newer replacement evident by the nice blue. Barrel also has nice blue as does the receiver. Barrel has a near perfect bore. Rear sight is a pre-64 type. Wood is VG overall. Action works good. Would be a fun gun to shoot!
