AH. Thanks
SurferRosa . I saw in the archives that
Wildwood had a Falcon like mine but didn't realize that it's now in the hands of
Mr. 66 .
juvela I'll bet you're right about this one being sold as a frameset with just the
Tange Falcon headset. I've seen a few online ... frame like this with that headset, so it seems to be more than just a coincidence.
I couldn't find catalogs online past 1986, but I'm including a picture from that catalog below. Not quite this bike but not too far off.
As far as
Reynold 531 Competition goes... I found an old post by
verktyg with a chart where he said that the super light
Reynolds 531 Competition was the lightest that they were making at the time.
Anyway... here are a couple of other interesting images I find while poking around online.
