Seaplane i.d appreciated…

Hi All..I’ve been a collector of aeronautica over the years, mainly those brass or chrome aircraft on ashtrays and have about 35 now.
I have the fuselage and lower wing (only) of something that looks very Supermarine’ish, and if anyone can i’d it closer that’d be great.
It is cast brass, weighs about 3 kgs with a span of over 12ins and fuselage around 11 ins long.
Would have looked absolutely magnificent when it was complete I’m sure…
