Assuming the factory made only the one pink, then according to Charles Hajdamach this is 'rose-du'barry', and might have been made anywhere from the early 1920's until well into the 1930's. If I'm wrong and this is Richardson or Frederick Carder, please shout.
If you compare the picture in Charles Hajdamach 'C20 British Glass' with what is presumably the same product in Williams-Thomas, there's a lot of difference in depth of colour - the latter being much paler. I've tried to keep this one life like, and it does look much more like the Hajdamach picture, although it's just possible he's over-cooked the colour slightly.
Only a tad over 3" (75 mm) tall, and not really sure if it's supposed to be simply a decorative piece of glass or whether it did have a practical purpose, but it shouted at me from the charity shop shelf, so couldn't leave it behind.
I believe some of these S.&W. examples are marked, although there's nothing I can see on this piece.
I have pieces in blue, green and now pink, so only cinnamon and cream to go
