That wing shape is most 'UN-Russian' to the eye, but the overall shape surely is Russian. Great modelling of an obscure type there Thomas.

Thank you, Kit, but it is not as un-russian as one might think. The original T-10, on which the Su-19 was more or less based, had a very elegant wing shape...

Oooh, I like that! Did they fly the T-10 with that wing shape? I've only ever seen side-on piccies of it.

Facinating vid that, thanks for posting Thomas. 

Why didn't they continue with that ogival wing for the production aircraft though? It's interesting that the T-10 has two very large wing fences well inboard on the wing, and I'd always thought that ogival wings didn't need them because of their vortex producing capabilities.

I think it's the wing roots/LERX/BWB that actually gave the most benefit (esp. at high angles of attack), and which was taken over to the Su-27. The T-10 differed considerably from the Su-27 in overall configuration, and I think Sukhoi dropped the elegant wing tips in favor of missile rails. The basic wing shape is still there, though.
