Being afflicted with "What If" tendencies, I pursued a project to create a period 1939 "Playset" using various competitors toys. I know, shame on me but therapy still hasn't worked so here is the result of my effort.
Taking the Wyandotte Super Mainliner as the baseline I added another Airplane (Marx Twin Engine Transport) and a couple of "support" vehicles. The Marx airplane had been heavily damaged so an overhaul and an upgrade to DC-3 was an easy choice to make. The airport tug is Tootsietoy and the Fuel Truck is vintage Barclay loosely based on the Diamond T "Doodlebug". All the pieces have matching paint to keep the concept in cohesion.

Tom
