Paul thanks for your comments

I'm sorry but with all my googling I now can't find the two examples I found that had a gilt chain attached to three rings on the neck of their bottles. But mine has three nicked areas in the ...spelter... of the neck, one of which is like a broken ring. From that and seeing those pictures that I now can't find, I guessed mine was also supposed to have that. As to where it might hang, I have no idea why it or the others may have this chain and links, as mine I think, is far too heavy a piece for it to dangle off a chatelaine belt or anywhere similar really. The two others looked equally sizeable so who knows. Perhaps chatelaines were made of more sturdy stuff
