[CR]Can you help ID this 1980s "CBS" tourer?

An unusual bicycle (to us) turned up at a recent Trips For Kids auction up here and I'm trying to help the owner find out more about it. I've posted the pictures he sent at this link http://www.jimlangley.net/cbs_bike.jpg If you can identify it, we'd sure appreciate it. Notice the CBS on the seatstay caps and the shift lever that operates the Sanyo bottom-bracket generator. My best guess is that this is a Japanese-made bike but I can't place it (it reminds me of the Specialized Expedition). I imagine it has no great collectible value or perhaps even interest, but I thought someone might know of the company CBS. Thanks a lot for taking a look, and ride safe!
