Grandstand Convertors were only produced in the UK in 1981+. The Grandstand Convertors that are Diaclone based, are fully licensed by Takara and were put out by Hales Ltd. The toys are exactly the same with Takara markings. Other Japanese transforming toys were produced in this line. Strangely though they are packaged with the rubber tipped protected missiles which originated from Italy. Though there are slots for the the Diaclone drivers, the box was empty but showing slots for them.     This is Sigmatron, and he actually is quite cool. The toy stands 12" inches tall and " inches long in 4x4 mode. His transformation is unique and he comes with weapons! I have never seen this toy before, in any form, and it is licensed by Yonezawa Corporation 1984.     "Sigmatron is one of Omegatron's many followers. He is one of two warriors (the other is Betatron) whose great trick is to be disguised as an ordinary earth jeep, but then change in to an evil fighter robot to attack his enemies."
