WTB: HO scale Phase III Superliner Sleepers

[Ypsi]

Hey guys, this is a more specific item that I am looking for, but I figured I would ask here anyway. I am looking to buy a pair or 3 HO scale Walthers Superliners to finish off my phase III train that I started building this spring. I have 4 coaches, an observation, diner, baggage car, and hi level step down dorm/coach all in phase III, the sleepers are what I need to finish it off. I check eBay frequently, but haven't been very lucky in finding some phase III sleepers from walthers in a while. You can drop me a PM, or post here if you have any you would like to sell or anything. Thanks!
