PLEASE

If you want people to help you, I've found that being polite is a great help.
Can't find an exact match, but either:
http://letterheadfonts.com/fonts/monogramcircle.php
or
http://www.haroldsfonts.com/circle-monograms.html
with a slight modification of the E, are pretty close.

pilaster, where do you sign ?

If anybody has the official font, I would appreciate it. It is a font forum. Don't take life too seriously.

Sorry woodmc, but I've never come across an exact match to the SRC you seek. The best I can suggest is in the earlier post with Harolds Circle Monogram being the closest for the S and C. Modified E. If you happen upon an exact match, let us know as I'm sure we'd all be interested.
