GERMAN SIDEARM?? for I.D Please

[Atlantia]

Hi Stuart,
Suprised nobody else has chimed in to solve this little mystery!
From reviewing the pictures it looks like the blade has been in the handle for a very long time so I'd assume its original to it. I notice that it has a single tang pin, whereas the bayonet version would have had 2 plus the tang was full handle length incorporating the spring catch etc. The tang in your sword must be shorter by the look of it, whether or not it extends far beyond the pin. The pin is in the right place (as in the same as the bayonet). I've had quite a few Yataghan bayonets over the years and I specifically remember having one with the same solingen makers marks. I don't recognise the Gladius style handle though. I'm thinking it may well be a deliberate marriage shortened bayonet blade and gladius handle for a specific reason. The bandsmens swords often have lighter handles, and yours is the same scale as artillery or pioneer style swords which would make the short blade very back heavy I imagine. Have you had a chance to have another close look and see if you notice anything more?

Regards
Gene
