It looks like Roundhouse from the House General Collection.

See this image from the Script Font ID Guide:

It looks like a little outline editing has been used on the A, i and T (for example), but the basic font outlines are almost all the same. I believe Roundhouse was the starting point for the sample's lettering.

Wow, thanks.

Do you know any sites which sell this font on its own - without the whole collection?

And can you give me the site which your image was from i'd be grateful - so I might be able to see any similar fonts.

Unfortunately, House believes in selling their fonts only in packages, and only through their own site. I have written to them, and they seemed very clear about that.

My site is at bowfinprintworks.com and the part that sample came from is the Script Font ID Guide, Part 5.
