Thanks a lot for your detailed and knowing comments!
Concerning the surrounding of Gottfried Leygebe there is a similar sword in Seitz Blankwaffen II attributed to Leygebe and the Rapier (second from above) at Hermann-Historica (
http://www.hermann-historica-archiv....db=kat52_A.txt) which has a similar crossguard is attributed to the surrounding of Leygebe. On the other hand, the pommel-lion and the position of its legs is quite similar to those of the VOC-swords Mark mentioned, but the VOC-lionhilt-swords normally showing (as far as I saw them) a lion that covers the whole hilt. Also the shape of the flat straps does remember me on northern european/dutch swords from the first half of the 17th cent.
This relatively simple blade often occurs at german or middle-european broadswords (Felddegen) of the 17th century, more at simple versions than at officers weapons. But there also are a few examples for nicely crested swords using a simple blade.
Anyway, together with your statements I also think that there is a good chance that the sword descended from netherland´ territory. I am excited what Jasper and/or Micheal are thinking.
Thanks a lot and best regards,
