font script swash cursive calligraphy

Help with Swashes, please!

Please help! Are there any rules or formatting structures for using swashes to fill in negative space for a scrip or brush layout? Like are there any tips or do-and-don'ts of creation? I want to use some to add to my layout but i don't know where to begin or which ones to use if the font does not contain alternates or glyphs included in the original. Thanks in advance!

Script, similar to Bickham

I have attached a sample of the font I need identified, and it can also be seen at the link below:

All the lowercase characters are very similar to Bickham Script, but the uppercase characters are throwing me off.
The uppercase "E" seems pretty standard and can be found in a few English fonts as well as others.
But that "P" has a pretty unique style to it, so surely someone has seen this before.

Ive been searching through all my font books with no luck, so im hoping the collective wisdom of the world wide web can be of some help.

Maybe it is even a combo of different fonts.
