I think that it might be fun to dedicate a thread to some dramatic "before & after" restoration photos. My apologies in advance for overlapping or replicating prior threads.
The idea here is to post your favorite restoration.
Mine is the trashed 1950 Gottlieb Spot Bowler, shown here. The restoration was arduous, both mechanically and cosmetically. I'm proud to report that it's now in the Pacific Pinball Museum.
