The Panasonic pictured above is actually a Sport 1000. I believe it is a 1985 based on looking it up in the catalog and the color is Grape Dust.
The Tubing is Tange Chrome Moly Double Butted.
Here is the link to the Panasonic catalog.

I happened to get lucky and find this one. I (or my wife) would have been just as happy if it was straight guage steel. My wife would be more impressed by the color and condition than the frame tubing. She is probably smarter than me about what is important.
