I'm thinking the black one is a 62 it has a 11/61 hub date.
the ladies blue bike is a 61, I don't remember the blue mens, but I think it's a 61 as well.
The ladies bike was on ebay as a shwinn travler with a minimum bid of .99. and shipping of 150 I think. I had that bid at .99 for a few days before I emailed the guy and told him I'd come get it and give him 20.00, because that's how cool I am.... he agreed, then told me about a few bianchi's he got in a storage unit buyout. I told him that nobody likes those crappy green dego rides and that I'd buy them for 20.00 each sight unseen. he wasn't too keen. we'll see though. I don't imagine even a Bianki Champion bel Mungo would ellude any savvy ebayers.
