It's just my luck that they are unusual and I've tried extensively to identify both the maker and the Assay Office but, without success. All I know is that it's not a UK hallmark.
The ring is an 18 carat plain "D" profile wedding band measuring 5.5mm diameter x 18.5mm ID and weighing 4.6 grams.
The maker/sponsor is E.T. followed by a plain cross that looks like a large + sign. I don't think it came from outer space though:) The year letter is a serif capital “L”.
Not finding the makers mark wouldn't be too bad but the Assay office mark is not very clear. I have tried many different ways to improve the clarity of the photo but this is the best it gets. The shape is similar to a bloated, reversed Y", but it’s not symmetrical. The closest mark I've seen is a French cockerel but I'm not convinced. Without the Assay Office, I can’t tell the date.
I would be very grateful if anyone could help me pin it down.
Thanks,
Richard
