Vladimir,
I understand that there is no "dog leg" like the Model 1930, but on a conehammer there is no "ring" or "step" in the barrel. It is a smooth transition. The photo that I assume that you used for your 3D drawing has had the barrel replaced so there is not a smooth contour. The barrel should look like the bottom re-touched image:

I understand and complies with you.

The stock in drawing needs to be modified to fit the 20-shot gun.

Surprisingly it took Mauser more than 30 years to realize removable magazine being the way to go. Why did they stuck on fixed magazine well is a myth. Probably because the feeding system was boss' invention so it stayed. After Paul Mauser's death in 1914.... this still kept unchanged for so many years.

Greetings, I have just joined your forum tonight. I am the person that has the C-96 fixed 20 round magazine for sale on GunBroker. As I understand it, Vladimir wants more pictures of my C-96. I shall email what I have.

I thank You much.
Thank you

Bill,

Welcome to the Lugerforum! Hope you enjoy yourself here among fellow collectors.

Bill -- Sorry that I missed your earlier message from GB.... glad to see that you figured out how to get here. 20-shot Mauser is a super rare gun and surprisingly, two collectors (at least two! you and Albert) have it in this thread. I have seen it in books and periodicals, but have never seen a physical one. There are quite a few Spanish fixed magazine 20-shot pistols (Astra, etc) in a museum, but I did not see a Mauser 20-shot there. Since local people have never seen a real Mauser 20-shot, when they mention the adjective, the term actually refers to Schnellfeuer which was very common in the museum.

Welcome to the forum.
