Excuse me for using these photos from its Ebay listing, but they're likely better than I can take myself. I just purchased this Imperial bayonet made by and marked J. A. Henckels and dated 1917. This is exactly how it came, but my question is about the unmarked frog which to me looks like one from the Third Reich instead of earlier. It seems to be brown on the back (though that might just be unfinished leather) and black on the rest. As can be seen, it has been repaired by the replacement of one of its rusty steel rivets with a shiny aluminum or zinc one. Although there are no serial numbers on either bayonet or scabbard, it appears to have the same inspector's initial on the pommel of the bayonet and the finial of the scabbard though they're both very faint. Also, was it usual to paint the scabbards of Imperial bayonets? Any thoughts or information would be appreciated!
