Strange gladius

[Youngster]

I've found the sword in Miks.
I'll do my best translating his catalogue entry for it.

Cat. A482
Findspot: from the Rhine near Mainz-Weisenau
Museum: Mittelrheinisches Landesmuseum, Mainz (Inv. F4070)
Type: Gladius (dagger-form), "triangular"-type, lentil-shaped blade
Measurements:
length overall 556 mm, blade 396 mm long and c. 46 mm broad, tang 160 mm long
pommel: c. 44 x 46 mm
handgrip: c. 26 x 83 mm
handguard: c. 34 x 5 mm
The handle is made of three parts of bone.
According to an older publication there was a copper alloy suspension fitting in band form still with one ring found with the sword but was not mentioned furthermore.
It is not dated.

Is there a picture with that listing? Can you screen shot it? I reverse image searched it and found that another pin (using the exact same picture) claims that it is an original blade with a reproduction hilt. I'd be more inclined to believe that story. But who knows if it has any basis? I'm still more suspicious of the blade than the hilt. If that blade is original, it must have been cleaned very aggressively to look like it does now.
