Inspected the bike this morning. I've got to say it's pretty nice. Wish I was in the market. 53cm frame with paint in quite good shape. My size but I'm not really in the market right now. There's a pretty decent scrape on the left side of the fork but other than that it's held up real well. Owner bought it used in 1983 in California. Serial number seems to indicate 1981 production. Components are original from when they purchased the bike. I forgot my calipers to measure the seatpost in hopes of identifying frame material. Owner stated he remembered something about 531 from when they purchased it. This was his wife's bike and it's probably not been ridden for the last 15 yrs. Suntour Cyclone long cage rear derailleur and a Shimano front derailleur. SR crankset and stem. Gran Compe levers. Wheels are 27" which was confusing to me considering the bike seems too nice for that and I was expecting 700c.

The frame has double eyelets on the fork and dropouts and a second set of bottle cage braze ons under the downtube like you'd see on a touring bike.
