Earlier in the Spring and grieving over being knocked out of the running for the JR21 Atomic Submarine Aircraft Carrier, I purchased this unusual and diminutive JR21 piece of obscura to make me feel better! I haven't seen another of these JR21 beauties, which has the JR diamond cartouche on the underside and never seen a box. What I have turned up is the virtually identical and far more commonplace 1967 SCALEXTRIC TYPHOON COMBO, which came in a whole range of colours as pictured below. I suspect that the Scalextric toy came first and JR21 followed. Were there other JR21 colours made?
