Re: P38 values question
Generally, and all other things being equal, the 41 date will bring more than the 42. The reason is that the earlier the date, the better made the gun and the finer finished. The ac 41's (no makers other than Walther at that date) were beautifully finished and blued, with actions that are like a fine watch. There are a few weaknesses that were later corrected, but overall, given the choice, and again, all else being equal, I would take the 41.
Original magazines are going for $45-60, more for some early ones.
