Yes, it is a rather interesting Sowerby design, pattern No. 2437, launched, I believe, in flint (not colour) and in three sizes in the company's 1927 trade catalogue.
You need a bit of history to appreciate this design. The Adam Dodds following was the grandfather of Adam Dodds, without whose contributions this glass message board would be a considerably poorer forum. Adam Dodds, Sowerby's general manager from 1907 until his untimely demise in 1929, was responsible for the launch of Tynesyde Glassware in the late 1920s. After a Czechoslovakian designer by the name of Schottner and two Czechoslovakian mouldmakers joined the company, the range expanded with the launch of many new designs every year from 1931 until the outbreak of war. Tynesyde Glassware is a mix of classic Art Deco, milder Deco styles, and imitation cut - an interesting reflection of the conservatism of the principal customer base - the British public.
I am not entirely sure whether 2437 was pre-Tynesyde Glassware or not. If it was then it is a fairly classic late '20s design incorporating swags and not attempting to emulate cut glass. If not then it was an mild Deco design aimed at the cheaper end of the market. Whatever, it survived into the Tynesyde Glassware range of the 1930s.
All of these I have seen have been the 7½" version in satin pink, probably dating from the mid-'30s, and all probably one big order from such as the Co-op or Woolworths.
I would not recommend it as an investment - it is rather difficult to sell. However, any Sowerby collection without one is missing out on a classic example of the transition to Tynesyde Glassware.
Watch out for other versions, which would be more attractive to collectors. In particular, the two other sizes and examples in Carnival glass, all of which will have a scarcity value. Also watch out for pattern 2437½ from the same mould but slightly less flared.

I can't think of anything else. Hope that is okay.
