Here is the description:
A Mini Johnny Model RARE AS IS & lobby card This one of a kind Mini Model was used in the film SHORT CIRCUIT 2 It is now in 4 parts. It used to work on the movie as you can see from the switch and all. It needs to be put back together. It appears that the arm that is unnattached is missing , but it still has the hand
The item is already at $1,500 with a day to go but it sure looks like a production made piece and clearly there is alot of interest in it.
