Excellent result, and stunning to say the least!
I would hazard to guess you have spent a serious amount of time on this restore - perhaps more than any other you have done, or at least up there?
Without doubt, this is the most exhaustive restore I've even done. 1960's Ballys (especially 4 Player games) have a lot of work that needs to be done - more than GTB and Williams of the same era. This game is the oldest I own, and was selected as it was the "worst" of the first container - so it was a good measuring stick to what lies ahead (over 45 EMs). Hving said that, there's two challenges I've answered - Nickel / Zinc plating and playfield touch-up and clearcoating. This opens up many opportunites to attempt machines in far worse condition, and I look forward to clearcoating many playfields "old school".
I'd say I'm approaching 200 hours.
