Black and clear glass perfume atomiser with bubbles

I've had this little perfume atomiser forever, waiting to source a rubber bulb thingie for it (but that's another headache I won't trouble you with).







I understand Whitefriars did some glass ware with bubbles, but that's as far as I've got. Any clues on a date and maker would be fabulous, thank you!

The bubbles are quite chunky and aren't aligned or evenly spaced, which makes me think of Eastern European / Far Eastern production.

But it's not really my field, so I might be wrong.

Thanks Nic. I've certainly got no high expectations that this is a collectable piece but I thought it might date from the 1950s.

I forgot to add that it stands about 2¼ inches high, not including the metal fitting, so its pretty tiny!
