When this lovely little thing first popped up I thought (and hoped) it was a Roman duck brooch. Trouble is, the underside doesn't seem to match up with the brooch theory and now I suspect it's more likely to be a mount of some description. The "legs"(which are bent in such a way as to resemble Morecombe & Wise doing that dopey dance of theirs) aren't suited to contain a spring mechanism and there's no residue of a catchplate.
Not that it means a lot, but the patination is typical for that field with regards most Roman finds. Against that is the fact that it's in far better nick than Roman stuff invariably comes out like.
Basically, I'm stumped and would appreciate any avenues to wander down with regards an ID.
Many thanks
