My grandfather bought this sword from an antique store in Czechoslovakia in the 80s and now it is in my collection for me to take care of! To me, the sword looks similar to the parade swords that the Wehrmacht had, but just with the insignia filed off, as it does look as if there are filing marks on where the eagle should be and that spot is noticeably thinner than the other side.
I’d appreciate your opinions a lot, as I’m not 100% sure on this one! The sword in question is the one on the very bottom in the last picture. (I will post about the other sword that is visible in one of the pictures, as soon as I find the section that a Czechoslovakian sword fits into! cool militaria )
