Cuphilt Sword with Damascus blade?

Actually that is a wonderfully placed suggestion, and this arming sword is indeed in line with 18th century Portuguese and Spanish cup hilt arming swords.
The pattern welding though, I think remained known in Germany, ironically where its process nominally was begun with Viking swords many centuries before. The process was clearly not regularly carried on but it seems that there was experimentation trying too reproduce the wootz blades of India and the Middle East in the 18th c.

I am not sure with the wootz predomination in India that pattern welding would have been done, but again, the Goa suggestion is interesting.

The pommel does seem more European, and the plain unturned quillons are notable.
