Martin Model 207?

[OldGeezer]

I've stumbled across a reference dated 10 September 1943 to a "Martin Model 207-2A" but I haven't been able to find out what that might be. Does anyone have any information?

Martin Model 201 - design project only, 2-engine high speed attack/bomber (slim fuselage with fore/aft engines in line driving contra-rotating props)
Martin Model 202 - 2-engine civil transport, aka Martin 2-0-2
Martin Model 203 - design project only, 4-engine high altitude heavy bomber
Martin Model 205 - designation for planned Martin built production of Northrop B-35 'Flying Wing'
Martin Model 206 - design project only, 2-engine patrol bomber
Martin Model 207 - design project only, 2-engine long-range escort fighter*
Martin Model 208 - designation for planned Martin built production of Boeing PBB-1 Sea Ranger
Martin Model 209 - design project only, 4-engine long-range bomber
Martin Model 210 - AM Mauler

* intended for the same requirement that resulted the North American P-82 (I think)

OK, thanks! That put me on the track. I found sketches and descriptions in Buttler & Griffith's "American Secret Projects" and they weren't at all what I expected. Twin engines, yes, but a nose-mounted contra-rotating prop that makes it look like an oversize single-engine aircraft. And those 2 engines were V-3420s, so really more like 4xV-1710s. Wow!
