Dutch and Gibson,
Look at these two chamber drawings. One is the Swede and the other is the Swede SKAN. Now being that Larry has gotten a few people slightly heated here I'll take this opportunity for some insurance for myself. These chamber drawings in no way refer, suggest, or even hint that neither of you two don't know of them. They are just here for information about Swede chambers. I also feel of all the European Mausers that the Swede's generally were more uniform in their dimensions.
