Granny and the Gators

This is a VERY hard game to find!
Granny and the Gators and Baby Pac Man are the only two vid/pin games made by Bally.
You control Granny as she rows up and down the river, avoiding obstacles along the way.
The machine is in excellent shape, I would say 9.5 out of 10.
This is the first Granny and the Gators I have come across in 14 years.
