This sword is for sale at an local auction in a couple of days and just by judging this picture, what kind of sword is it?

There is only one picture available unfortunately….

They said that the sword is marked “Robert Klaas, solingen” and that is 92 cm long.

I dont know the starting price so it would be good to know what a sword in this condition might be worth. So that i’m not payin an overprice.

Hope that the pic is atleast some help.
