Pete, is there any doubt in your mind that:
1) This is a reblue
2) Most of the writeup is mythology i.e. Used to distinguish 7.35 from 9 MM magazines (why? they are interchangeable)
3) This may be based on a 1920's grip safety model like the one on Simpsons at

Would be nice to get a close set of photos of the proofs and the navy sight.
Is there a record of 2500 commercial M1904 pistols? That volume of STill is packed in the moving stuff
