Judging from your location I would guess it is a blade made for the Austria-Hungarian army in the 19th century, although "Weyersberg & Stamm, Solingen" apparently also supplied blades for the armies of other German states.
If you don't get a reply here, I would advise you to pose your question on the Sword Forum
. These guys seem to know their stuff, judging from the hits that came up about Weyersberg when I googled it.
If you do, and get a reply, I wouldn't mind if you posted the result here, since one gets curious.
And btw welcome to the forum.
