Pinball machine
 

I have what seems to be a 1967 Gotlieb Groovy 4 player pinball machine.Was wondering if anyone knows anything about these.Thinking about selling or trading for some parts.Machine is original unrestored.It does not work.Person I got it from said it just quit working one day about 20 years ago.Could be simple fix maybe.Dont know anything about it.It has nice artwork with flowerpower and other related 60s to 70s theme.Any help is appreciated.Thanks.I can get pics later if needed.http://www.marvin3m.com/gtb/groovy.htm Here is a link.Mine is the 4 player groovy one.

Does anyone have a clue on what this thing is worth.Any suggestions on how to find out.Any help will be appreciated.Thanks,Randy.
