Very rare to see them on sale, so you will need to be patient. They do appear from time to time, and if it is a dealer, at massive prices. They are often not original, wrong legs etc etc.. They appear on eBay, again - overpriced. Sometimes you can call dealers etc to see if they have any leftovers, as some dealers don't know what they are or their value. I agree with other comments, sometimes you need to gain access to collectors. I would start with Michael Shalhoub "Pinballmaster" in NSW as he has MANY contacts in the industry. The guys at "Pinball Rescue" have access to MANY woodrails, and if you could ever speak to Alan Tate in Queensland, you might find machines as he has hundreds. I waited decades for my woodrail collection, and would find it impossible to sell any of them as most a SUPER rare. BUT - they are harder to play than other games, and that is one of their advantages - only good players can play woodies.
