my sword with the Passau wolf, sure a straight model,
just for show the mix with old blades and later mounts...
your blade,  with his european type engravings and his ottoman-indian yelman influence can maybe be as old as mine ( saw really old karabela's blade like that... )
and picture of blake's red dragon.. 
a dragon order/ Societas Draconistarum  sword  ?  
  
Kind regards
