Cup hilt rapier, need help

[Roland_M]

Hello,

today i have an elegant Cup hilt rapier for the forum, i think from Spain or Italy.
The blade saw more than one duel, both sides of the edge are full of nicks from attack and parry. Only the upper half of the blade has nicks on both sides of the edge, this gives us an idea, how the blade was once used in duel.
The feeling and control of the very flexible blade is incredible, the point of balance is only ~2 inches (50mm) after the cup.

The fullers on both sides have latin inscriptions, which i cannot translate completely.
One side: FIAT FIDEDLIBUS
Other side: FAIT FIDELITAS
"FIAT" and "FIDELITAS" are clear, but what means "FAIT" and "FIDELIBUS"?

Measurements:

Length: 47 inches (1200mm), blade only: 39,5 inches (1003mm)
Weight: 37 oz. (1050 Gramm)
Point of Balance: 2 inches (~50mm) after the Cup

Any coments are welcome, concerning the age of the cup for example. The blade is around 1650 (?) but i am a little unsure about the cup.


Kind regards
Roland
