If you stump Arthur (it MIGHT be possible!) you can also try:
Automated WhatTheFont thingy:
http://www.myfonts.com/WhatTheFont/
Or the WhatTheFont Forum:
http://www.myfonts.com/WhatTheFont/forum/
...where many an Arthurian Font Wizard is known to lurk.
There are a few other forums out there, too, but these are prolly the best.
The stitched sample wouldn't work with the automagic thingy, but the Arthurs in the Forum would accept that sort of input.
(And BTW-- It looks like Arthur's been busy-- Several great new YT's since last I checked!)
