Frame mark on artillery luger.

What is a MAUSER BUMP?

Can anyone explain to me the real thinking Mauser had when they produced their early Lugers with the No Mauser hump and then some were intermixed with the Mauser hump and finally all were produced with no Mauser hump or bump?

The early MauserÃ¢??s had mixed humps and no humps, but for instance, the G dates seem NOT to be humped, but they all have a thickened back where the hump is, to better contain the rear axle pin during the rearward most movement of the receiver forks. The humped Mauser simply had some of the thickened rear frame REMOVED to form the hump.

I have no pictures of the Hump but it is formed at the very rear back of the frame above the lanyard loop. The back of the frame on DWM's is straight up vertical. Some K-dates, G-dates and 1936-S/42 MauserÃ¢??s are also straight up or vertical. The Hump causes the rear of the frame to not be vertical, it has a curved appearance to it. You can easily see it from the side. The Mauser Military Lugers are the only ones that have the HUMP, I think! It is interesting Mauser elected to remove that section of metal to return the frame length to the same as a DWM Luger!

I believe quoted from Ted, but not positive, here is a picture of the Mauser bump:
