Picked this one up locally a few years back. Supposedly the guy that had it, has the matching numbered mag to it, but cannot find it. It still has the sharp radius on the front sight band and it also has the large "S" in the S/42 on the toggle as found on early 36's.
I have been asking about the mag, maybe once a year. At first he was amicable with me calling, but the last time I called he seemed annoyed about it so I've given up on it.
