small sample - but I’d guess the same as above.

It's hard to be sure these days as OpenType fonts get smarter and add more alternate forms, but I think this is just what you say, handwritten.

Jan beat me to it. This lettering can't be purchased. It's written by hand, not using a font. Here are some font ideas:

Burgues Script
Bickham Script
Polonaise
ITC Edwardian Script

But the best way to emulate this look is to hire a good calligrapher.

Where can i find it?

Thanks everyone.
