With all due respect, I would guess that the number of model number, even for 30 lb gas coin op....is longer than would fit on the thread here! There were possibly many similarities, so some of the old timers may be able to give you some hints. Stay tuned,
Seems to me that a 14 year old coin op has probably used up 8 of its 9 lives. I hope you get these for a song, because you wouldn't want to shell out serious money, and within weeks need new motors, gas valves, etc etc.
