We know silver foil was difficult to cope with because it reacts if you don't keep the temperature low enough.
And we know Michael Harris and William Walker worked out a way of using it, but they defintely were not the first.
Who else succeeded, before they did?
That'd give you a short list.

We were cross posting, Greg, but what I said stands. (or wobbles about a bit)
I've now looked at all your links.
The lot after to the first Fieldings one, is more like your shape and has unusual external features.
The muilticoloured things don't have celery handles, and they're decidedly spotty, rather than mottled. The foil looks more "crudely" worked. They're rather lumpy and appear to be made from thick glass, compared with your rather more delicate thing.
