Swords

[Dolphus45]

I have two swords that my grandfather left me and I have no idea of their origin or value... there's an inscription on the handle that reads FG 98121 and there are some other marks on the handle... any help?

they also seem to have been used in battle and can be fixed to a musket... approx. 3 feet in total length
