Here's a scan from the catalog:

I just got this catalog last week and I'm mesmerized.
Please excuse the fixation. I think it's temporary.     

Thanks

Excellent catch Mike. (I hope the yellow-eyed smilies are
temporary as well. Ahem.)

From Solotype catalog again: Georgian Initials.

It only shows letters A through G, but the C and E are perfect matches. Don't know if it's digitized.
