I uploaded some pix to photobucket.
Model code is PFN10 (with 54 after it). Serial number is 0899316. Only 7 digits, but it seems to be a 1980 model. Correct?
The bike is a bit small, but I think I could make it work with a longer seat post and stem. The tires hold air believe it or not. I rode it up and down the street.
