Dave, I agree with the comments of John S & Pete above ---- shoot & enjoy, as no collector value. Unually a M1906 grip safety frame with just have a 5 digit numeric serial, but yours may have been renumbered. Also, the receiver marked "made in germany" were not marked that way until 1923 & later. I have all of the parts that you seek and price will vary with condition. In this case, I wouldn't suggest paying a premium for parts with a minty original finish.
