Hi All - any help appreciated with this shell back tablespoon. The maker's mark is LB and is clear, but can't find any LB in Jacksons that fits the time frame. The rest of the marks are very rubbed. I am assuming it's London, but there are only three marks - the second mark looks to be another set of initials, and the cartouch may be wrong for a lion passant, the third mark is unreadable and could be anything, leopards head, thistle, etc. So spoon could be provincial. Am assuming time frame of C1750 - Many thanks Frank
