Lenum:
Here are some obvious things that are wrong with it:
*The upper crossguard etch appears to be one that is often seen on post war pieces. We'd need a better picture to tell for sure.
*The lower crossguard is a pure fantasy piece which appears to be made up of a crossguard with perhaps a cap eagle attached.
* The blade is a known postwar pattern probably from Reddick
*The leather covering covering on the scabbard is totally wrong. The correct leather would be a medium to dark brown.
There's probably other things about it that are wrong that would be apparent with a hands on examination.
