Thank you Trev for your rapid and value added answer. I am disappointed I was wrong again. Perhaps I should go back to fishing. The upside is however that I seem to own an over 200year old Exeter spoon.
From my understanding of Miles Harrison’s Exeter cartouche article, this spoon cannot have been assayed before 1804 when the ovaloid lion passant was first used and was unlikely to have been produced after 1806 when the odd shaped duty mark should have been replaced? Could the rider to this be “John Legg” was working in Exeter as long as 5 years before his normally accepted dates of 1809 to 1814?
Reading around the cartouche article, I noted the photo in a 2008 post that you had uploaded of the marks on one of your Richard Ferris spoons. I thought its ovaloid lion passant with the broken tail was much like the lion on my spoon and possibly the spoons were of a very similar date.
Anyway how amazing it is that with a few actions of your keypad you have given this “no fixed abode” spoon from the bottom of my box a home, a father and almost a date of birth.
