I have a remarkably nice 1969 Bally On Beam I'm looking to trade; sorry I'm late to the party here but I might be able to make last-minute arrangements to send it up there (and bring yours back) with someone from Florida who's heading up to SFGE. Info / pics / video of my On Beam located at https://pinside.com/pinball/market/classifieds/ad/64557
Send me a PM if you're interested!
