The “Pregnant Guppy” was the first in a series of Guppies produced and operated by Jack Conroy’s Aero Spacelines.
I built the model using two Academy Stratocruiser kits, since the airplane had a stretched fuselage. The most challenging part was building the upper lobe of course, but I found a way to heat-form styrene sheet over a piece of plastic pipe to form the midsection. The “forehead” was shaped with bulkheads, which would later receive Apoxy Sculpt as a filler. The rear tapered section would be vacuum formed over wooden molds.
