Great site. Some were from Aberystwyth, others Derby.  Unfortunately I can't see any other examples of the embossed Gyde stamp

Hi AngelFish,

Brett Payne, the author of the webpages to which japeflakes and dublin1850 provided links, is a Rootschat member (username: Brett). Maybe you could PM him an invite to your thread here, to see if he can provide any input?

Rgds,
