Victorian threaded amber glass jam/condiment bowl in silverplate holder

I had to post something extra special for my 700th post, & fortuitously, this piece came into my life at just the right time.
A Christmas present to myself, actually bought in person for once, from a dealer who's supplied me with many fine items over the years.
A few months back I posted a fancy Victorian condiment bowl & was pretty sure I hadn't seen another one fancier...until now!
It is made from pale amber glass with unusual applied white threading. The crimped top rim has an applied pincer work crest. Base has a neatly polished out pontil mark.
Even better, it has the original silver plate stand, which is of Australian manufacture, & of a rather unique form.
The decor & finish of this bowl suggest a top - flight maker, as the quality is outstanding.
Not sure if it is of Bohemian or English origin...I'm leaning slightly towards Bohemian at this point.
