Need help identifying this German bayonet and scabbard, pretty sure from knowledge the scabbard doesn’t go with this bayonet but can’t remember what it belongs to, also the bayonet need help identifying thank you!

Sold this card on eBay to a buyer for 5$ and he’s coming back to me letting it know it’s fake, wouldn’t think a card like this would be worth faking but then again I could be wrong. Any help would be appreciated thank you! :))
