The Vintage Airstream Club website has the manual for a 1966 Overlander. I would venture to guess the Tradewind that year wasn't much different. On page 44 of the PDF document it says, "The toilet in your Airstream is a Thetford Slide-o-Matic, designed expressly for travel trailers." But that's about all it says.
my '67 has the original Thedford toilet and I found all the parts to completely rebuild it at my local Ace hardware store. I bought the parts about 3 months ago,cost about 150 bucks for every moving part.
