Hello Kuduae. I suspected that my Sauer-Mauser maybe one of the early transitional actions. I have read a bit about them in Jon Speeds book but do not yet know enough about Mauser 98's to say with any definitive authority that it is one of these actions. I will post photos but right now do not know how to do that. If someone is willing to talk me through the process, I will make an effort to do so. Thanks for your help!
