Reworked 1916 Navy

[mecano44]

Hello everybody

I would like to get some advices about this reworked Navy

It has been reblued no doubt, very close to orinal

Barrel is not original. Toggle shows severla markings of ( what I guess ) salt water corrosion

Magazine is not original, trigger is not matching, firing pin is not numbered and grips are not original ( after 1945 I think, because got once a new pair very similar)

I have some doubt about the frame, which is short type, because the 1916 on rail is lacking. The "ears" on back of frame are from a different shape as those of all my pre 1918 Lugers, not as flat on top but some slightly "rouded " ....? otherwise all dimensions and details are similar to pre 1918 frames ( very different from Mauser frames)

Serial is 1748 , and 48 can be found on toggle parts, and other parts on frame.

Other strange detail the "eagle over N " between the navy markings ( apologies for chalk powder )....
