German Sword-Engraved blade "In Treue Fest" WKC WW1 or WW2 shiny blade no rust

I believe this is a ww1 Period Imperial Bavarian Infantry Officers Sword-Engraved on both sides with "In Treue Fest" their motto. It has the initials WKC with knights head. It is in very good condition. It was brought back from a soldier during ww2. Buyer to pay shipping-to be determined. NO Rust on Blade
