Kutter,
I had 4 of the 1904 Paraguay Naval cadet military rifles, three of which came from the same 1960s retired gun dealer and were missing the bolt head (with front part of firing pin). The fourth came from a college friend and is complete. All are 7x57. I sent one of the actions to someone that wanted to study it and was interested in buying it. To make a long story short, I never got the action back. Consequently, I have the (uncut) stock with most of the hardware left, and it may meet your needs. PM me and let me know what you think. Be advised that all of them were in rough shape but, except for bolt heads were pretty much complete.
Mike
