German K98 Bayonet Wa4883 FNJ 1940 WWII with frog matching scabbard

Description

German K98 Bayonet Wa4883 FNJ 1940 WWII with frog matching scabbard.
This is old. It’s used and will show use. The blade is surprisingly clean and rust free. The serial number on the blade 3253m matches the scabbard. I don’t see any markings on the frog. Everything on bayonet is tight. This seems to be in good shape. Look at the Photos please before asking questions. It is stamped FNJ 1940. Another stamp of Wa4883.
As far as the history. A customer traded this, a helmet, gas mask and rifle. His uncle brought them back from Germany. He had some other items as well. All were legitimate WWII items. That’s all I have as far as history of the  item.
