Hello Woodsy
This is the toy that got me hooked on collecting space plastic.
The Supersonic Jets Set.
It's another example of the English reuse of American moulds, in this case Marx and Pyro. I was addicted to tin robots at the time but a hoarder's instinct made me put this to one side.
The set comprises three Marx copies, the #1 Double Gun Plane, #4 A Wing, and a Car of the Future. The fourth spaceship is the odd-man-out, a Pyro copy Rocket Car that's a bit more solid than the others. For researchers the label is priceless, proving that all four belong together despite their different origins. The set comes in a plain cardboard box with a paper label.
The plastic is thin - they feel lighter than Tudor Rose spaceships, and they're very brittle. There's a translucence about them, unlike the more opaque originals. Out of the box I can't see them surviving for long. There's no maker's mark on the box though each vehicle is marked with a tiny Made in England in a circle.
I'm fairly sure it's by Kleeware, though I'd welcome thoughts.
