13thC seal matrix

Bird facing right with double long beak

Legend PRIVE SV (I am private)

Sent to our seal expert for his views

It’s another PRIVE SV, Chris. HAMP-EA9E0$ and SF-470BCD are particularly close with the upraised and spread wing. If you simple search “matrix bird PRIVE SV” you’ll find parallels. In this case I found it was much clearer simply reversing the original than looking at the impression — sometimes it’s like that!
