Hi - As you can see from the comments in your link, these mould blown BS pieces are typified by having machine cut and polished rims, and a full or partial impressed 'cross' on the base which was left by the use of four part moulds - your rough pontil though seems to be out of character and doesn't look to be found on other similar bobble type pieces. From what I can see in your pix, this piece doesn't have a cut and polished rim.
The only patterns/designs that I'm aware of seeing are pieces with a more decorative/ornamental use... bowls and vases, rather than this sort of utilitarian shape - although that doesn't mean this couldn't be one of theirs, but clear is not something that looks to be usual.
Yours does have the 'knobbles' running diagonally, which is correct, but it is known that other glass factories in other countries produced similar ranges at later dates.
I think the jury could be out for some time on this one, unfortunately, and I'm going to put head on block and suggest this one is not BS
