Very interesting, Spock I make no judgement on your dagger and would not without a hands on.
The lines running right round the scabbard fittings are considered a big red flag. Now I say that but boy there are a lot of things I like about this one. No all daggers are textbook. Touch a magnet to the scabbard body and tell us if under the leather it's steel?
Even if this is a real one it will be a hard sell in this market. Collectors are demanding textbook.
