Ronnie,
* See the attached URL for a post on the "Mauser Hump".
http://forums.lugerforum.com/cgi-bin/lugerforum/ultimatebb.cgi?ubb=get_topic;f=2;t=00 0112
* Almost got a line on this one.
* After seeing the picture/explaination at the bottom of the attached URL post, can you now respond whether your S/N 3404ns has a "frame hump" or not.
* Also, is the inside of the frame "in the white" or blued??
* One last thing: Is there a number or numbers on the inside of the side plate?? What are they??
Thanks,
Bob
