Hello,
I just joined to let you folks know I have a 1977 Wico Big Top machine in working order, though the rubber bumpers are deteriorating and need replaced (maybe some light bulbs, too). It was in my in-laws' house from 1977 until about 10 years ago, since then stored in our house (NOT in the musty basement). I stumbled onto your site after finding most pinball companies only work with coin-op arcade machines (not "children's toys" as one replied). US/PA/Philadelphia
