I didn't pay anything for it. I brought a Gorgar as a project pin when lockdown started as I had some free time for the fist time in 20 years to do something other than work! A friend of my Dads heard I was doing the Gorgar and he literally turned up at my workshop with it in the back of his van and said "I hear you like tinkering with pinball machines, I have had this one in the garage forever was going to throw it out, its yours if you want it". The reason i was trying to get a value on it was I wanted to buy him a good bottle of whiskey to say thank you but wasn't sure how good a bottle I needed to buy!
I'd say get on the Japanese stuff then as he's basically given you £1k!
