Thanks everyone for you help. After receiving the info from this group, I set about my task and still couldn't get it apart. I contacted a very young, new gunsmith in a surrounding town that uses the Mauser bolts in some of his custom guns and he, his Dad and I were finally able to get the bands off. We had done everything all of you had told us but it still took the 3 of us to get it apart. It was so crammed full of Cosmoline that we felt that the seal was just so tight it wouldn't come apart. I have been working on it since this morning and it is coming clean as a whistle. The serial #'s don't match so it's probably not worth a fortune, but I certainly am enjoying it. I have also been reading about the history of the Mauser guns. Thanks again for all your help.
