Folks, I just now saw this thread. Last year, I was looking for some hard to find Bachmann parts not offered on the official Bachmann parts website. I looked high and low and just happened to send a message to a guy on eBay that offered various parts. He did not have the items I wanted listed, but when I sent him a message he said, yes, I have those and he said that he could not possibly list every item that he has. He immediately listed the items I needed and I purchased them.
He is on eBay at http://myworld.ebay.com/sooo-m...id=p3984.m1439.l2754
and if you send him a message (email or whatever), he just may have the parts you need. If I hadn't sent him that message, I would never have found the parts I was looking for. PS: he also has (or had at the time) shay parts (trucks, lineshafts, etc etc)
good luck
