Unfortunately, without an Rd. No. or name. However, it does have a small cartouche on the underside in which are upper case letters FGC (I think) and opposite to which is the figure 22. There's also a figure 1 on the bottom.
I'm inclined to think this stopper is not the original - it's a blown example, as opposed to a solid pressed one like the others, and not a brilliant fit. Height is about 11.75" (300mm) including stopper. Might anone know what the letters stand for.
Probably another of the Cottle/Lang type of imported wares, but that's only my opinion. Thanks for looking
