You are looking at an early Grandstand converters Omegatron.
Before Hasbro started buying up the rights to all transforming robots this was it.
This was later rebranded as Omega supreme.
The robot is complete but unfortunately does not come with instructions. Battery's are installed and he works perfectly head moves and lights work.
The box is still bright and still displays well but is 30 years old so please see photos for condition.
Thanks for looking
