Thanks very much for the response Shanxi, much appreciated.
The piece is actually quite heavily corroded, and the features are only visible by introducing
side light to emphasise the features, so I think this is about the best definition I can get.
It would appear then that this is a late circa 305 to 400 AD then. There was considerable
Roman activity in the
area of the find during this period, so not entirely surprising !
If anyone has any further suggestions they would be most welcome !
Thanks and Regards
Chris
