Jack, welcome to the forum, the two who answered you are some of the two best sources I know of accurate info on Kriegs!
Plus, there is a book by Gibson, out of print but available still at gunshows or at Simpsons, LTD, specifically on Krieghoffs.
I collect stories on guns brought back from the war, if interested, and only if interested, I would love to hear how you aquired it? Traded for it from a vet, bought it or won it in a poker game in england, found in a supply room, etc. If interested, pictures and a short bio of you (credit of author always given), I am slowly making a booklet, have about 40 assorted stories and pictures.
Thanks and welcome again to the forum,
Ed
