Help: Have you seen this lost font?

I'll toss in this site as well:

They have the old Cassidy and Green fonts, which are now public domain.

That reminds me of Roughwork from Frontcraft. Roughwork is not as polished as your example, but is supposed to be more of a sketch-stage of the letterforms.

If you're looking for interesting fonts, give the Scriptorium a try! They have great collections of art by 19th century illustrators as well (also often paired with fonts from their handwriting and lettering [cool]), and a super celtic fonts and art collection (slightly more towards on-topic).
