Have a look at the ' 1 smart missile' insert...
Plus IIRC there are a few slight variations in colour with certain inserts.
Cool mines a prototype as well then. I always thought that it was just early production, dog of a thing to get the t-rex running right 100% of the time.
My Dino was missing the L/R motor, and there were other problems contributing to the Dino not functioning after installing a new motor. Out of all the games I've done, the Dino is the hardest "toy" to have fully functioning. The BEST thing you can do is upgate the game ROM, this has a modification that prevents the wear on the L/R motor.
The early production games also had a different jaw link and a different metal link underneath, this also wears the up down motor out quickly. I modified my game to be the same as late production and the difference to the t-rex up down is greatly improved.
