Ed...... I would think the + would indicate the spare mag. Thanks for the show and tell. I have a 41 byf 1622 Ku.

Second shot (if this working) shows the S/42.

This would suggest to me that the barrel was left over from 1935 (G-Date) production.

Last shot is of the 42 military holster that it came in. The stamp is Ku over a box that has K.A. 5 in it. I know some of you have seen
this in Automag but I thought I'd throw in up for any thoughts or
comments.
