Yep I agree 100% with that, but do remember I did not clean it as I mentioned in my first enquiry. Anyway an update on my piece after all this research, would you believe it I saw one today on Ebay in a VF condition with a good description and weight, all the same features as mine. Well that is that solved but have thoroughly enjoyed it, thanks to all who have replied to my request, now to start on my next piece. Cheers all It's even more fascinating than first appears. I've been trying to make sense of the reverse legend, left hand side. It seems to read "MAITT" which makes no sense at all, in English or Latin. But what if it is a conflation of MAGNA BRITTANNIA, or MAG. BRITT. = MAITT for short? I'm not sure when the name Great Britain was first used, but perhaps it was at the time of Union? Just a hunch. No it may look like MAITT, it actually has MAII.I which still has me baffled at the moment, maybe you can make sense of it now! Await your reply on this bit
