I am a resident of Australia and have been attempting to collect HO Circus wagons and other accessories from the Walthers Series. Has any complete, definitive list ever been generated? All of my models have come from eBay and I keep seeing different ones every now and then. I am wondering what is/was available and the kit numbers (release dates would be good too). There is not much information on the net apart from 'for sale' notices and as you can imagine that doesn't help me much.
