We collected 3 of these models and built up one that was nearly perfect.
We put enough parts together for another one that ran quite well, but was so bogus that it was hard to look at. From the movie, we named that one “The Stingle”
The remaining parts of the third one were sold off piece meal.
This was featured in our living room for many years. I sold it off in 2014. The buyer only kept if two years and almost doubled his money.
