DWM & Mauser Metallurgy

Interesting side story..At a yard sale in Yuma AZ once a guy has a Mauser..41 BYF I think..I am looking it over cause it's reasonable..then I notice a thin crack in the bolt. I look closer..the thing is cracked all over. Like it had been dipped in liquid nitrogen and hit with a hammer. Cracks so fine they were hard to detect but there they were.

Really scary story Jerry. What happened to the gun? It would make a great display piece!

I don't have Gibson's book, but IIRC this has come up before, and a member pointed out that not only are different parts of Lugers different hardnesses but also different alloys. This makes sense, as unstressed parts need not be expensive alloys or unnecessarily heat treated. And wartime manufacture would have led to shortcuts in quality.

I have John Sabato's blueprints CD but my German is pitiful; maybe someone with more fluency could see if the prints specify heat treatment???
