Hello all,
Thanks so much for your advised comments on this two handed sword. It appears that the coat-of-arms represents:
First quarter: Swabia (Germany) or reversed three passing lions (England) ?
Second quarter: Three Fleurs de Lys (French Royalty)
Third quarter: Kingdom of Jerusalem
Fourth quarter: Old burgundy, or Lord of Plouasne ???
The crown is a Royal one.
Could it be descendants of Ferdinand II

?
Thanks for your help,
