Jim,
I wanted to post another picture of a somewhat later Hungarian hussar sabre from around 1780 on which blade it’s engraved ”Vivat Fúrst Eszerházy.” Although breathtakingly beautiful, this sabre is not decorated with a pearl line along the knuckleguard.
On the other hand, this pearl line decoration does appear on the Hungaro/Serbo/Croat sabre from around 1750 which blade is engraved with letters of Old Slavonic. Its blade is no less than 5.8cm wide (!).
Finally, on Hungarian emigrés serving abroad, they played a part in forming most countries’ new hussar forces. They even crossed the Atlantic to the U.S.

All the best,
