I am new to the site having been searching for some information on a bayonet that I purchased in a yard sale.
It appears to be the Seitengewehr 98/05 variation from WWI. It was manufactured by SCHTEL & SACHS in Schwienfurt in 1918. It has has King Ludwig (Bavaria) markings on the back of the blade and on the butt of the bayonet. Oddly enough it has a clear plastic type handle with a 1930's type photo underneath on one side.
I am curious if anyone knows about this type of handle or might it have been modified at a later date by a German soldier.
