I've read of these a/c off & their mods/upgrades proposed. More powerful engines, raised cockit & 'blown' canopy, jettisonable wingtip fuel tanks. ISTR reading that some of the mods were later used in the A-26K. I've never seen any drawings of the proposals, only the descriptions. I've been considering building a model of one, of my interpretation of the descriptions. As for A-26K mods, I suspect 4 blade props instead of the fat 3 blade ones on the A-26K & I can't see the pointed, streamlined tip tanks either, maybe the basic teardrop shaped tanks of WWII vintage, only mounted at the tips. As for the raised cockpit & blown canopy, I can imagine the same treatment as done to the later P2V Neptunes. However, as many unusual a/c types that show up around here, I thought someone might have further info, like drawings or something. Anything, anyone?
