Hi again Oel
Have a response from the Goldsmith's Library link you gave me, but had been hoping to get some further explanation of why the particular maker was suggested There seems to be about 5 possible makers with the same mark around the right date. Any way their first response was as follows:-
" I think that the maker’s mark was the mark of James Barratt which was entered in June 1816.
If you would like to find out further information on the crest there is a professional researcher, Luke Schrager, who undertakes works like that. He can be contacted at
pursuivantresearch@yahoo.co.uk."
Thanks again for your interest and leads
Cheers
Doug
