Manufactured by Bell Radio-Television Corp. in about 1958, production ran until about 1960.
The Bell Colt 'Planet' may have been a dual-wave set although its unclear from the sales literature at hand. JWS states it was, yet on the opposite page in More Golden Age of Radio he has a brochure that does not refer to it as being 'world-wave', just 'Australasian reception', same as the Colt. Its likely that both were produced, given the lifespan of the model.
