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 Deltatron. Can transform into a F-15 Eagle Fighter Jet and back by remote control. The original company was Yonezawa Corporation. Was put out in 1984.

He is one of the slickest of the Convertors because he can convert automatically into a deadly motorised robot." Collection of: Anonymous Paragraph: Alex Bickmore Photo: Anonymous
