Is there a simple way to date a sword marked Weyersburg, Kirschbaum, Solingen on the blade? I haven't been able to find any other markings as to date or type of steel. It's handle is 6" or so long and the blade is 32" long inside a metal sheath. I don't have a picture available because it belongs to a friend. He found it hidden in a trailer he bought so I know nothing about it's history. Thanks, S1
