Yes, they are correctly paired - and they are both Sowerby. They were shown in Sowerby's Pattern Book - number 38 (1956). The bowl was described as a "Floating Bowl" number 2565 (that didn't mean it floated....it meant that you could float flower heads inside it). The figure and plinth were part of the whole set. Cottle (Sowerby Gateshead Glass) notes that Herr Schottner (a Sudeten German) came to Sowerby's in the 1920s and was possibly responsible for designing these items.
Colours - flint, amber, blue, green, pink. - with or without sandblasting.
I have the bowl and lady in a zingy vaseline. Of interest to Carnival collectors is the fact that the bowl (which can be found both cupped up and flared out) is known in a rich blue Carnival Glass. No Carnival figure has been found. They are hard to find, and oddly turn up in the USA rather than the UK. The bowl is known as Flora to carnival collectors (it has fabulous roses moulded underneath).
The figure is also sometimes called Flora...it gets complicated (I've written it all on our second CD).
There's a story that the bowls were sold full of Cadbury's chocolates - however I did follow this up some years ago when I was researching it. Cadbury's trawled through their archive but could find no mention of it. Maybe it was Rowntrees
