Thank you my dear Apophenia,

but you forget a VB-VT proposal,and for SEV-7.

... but you forget a VB-VT proposal...

Sorry hesham, I'm not following you on the VB-VT proposals.

Do you mean that there is an actual (or plausible speculation on a) SEV series designation for the Seversky VB-VT proposals?

On the blueprint documents, those VB-VT proposals, are identified only as 'Proposal 1' and 'Proposal 2' (or, in the title, as "Proposal no. 1 and no. 2"). What am I missing?

BTW, on my second SEV-7 entry, I have listed the actual output of that aircraft's individual R-1830-9 engine. Your snippet lists the performance promised by Pratt & Whitney for that model of Twin Wasp. Alas for Seversky, the R-1830-9 which P&W provided proved incapable of delivering 850 hp.

My dear Apophenia,

that's from the book, The American Fighter ?.
