Operation: Works very well, as designed. From what I see it has had little use. Roll ball to OGG if it enters the center Ogg moves forward.
If ball enters off center Ogg head opens tongue comes out and he backs up. Condition: To the best of my knowledge it is complete. No Box Battery cover in place.
Operates on 2 D cell batteries, ( not included) Battery compartment clean no corrosion at all. Overall I would say it is in very very nice condition.
It was found in closet storage, removed it from the closet, installed batteries, worked right away.
I don't know much about these, but I will try and answer all questions. Buyer pays 12.00 shipping. Delivery confirmation.
