Just an update, no real progress: I saw some pics of a Jeff Lindsay/Mountain Goat road bike, and nice bike, but too different from this one. Other suggestions from the intelligentsia suggest it might be Don Millberger (who was once in Orinda, then maybe Walnut Creek, CA) as well as a strong vote for it being TS Isaac, including the fact that he used a 7-digit serial number on a touring bike from (maybe) 1979. I can't find any contact info to email either Tim Isaac (last known in Woodinville, WA, but match bicycles shut doors in 2000)or Mr. Millberger. If anybody knows their email, please PM me. Lastly, the guy I bought this for is now having doubts about the project, seems he is leaning more toward Fix-i-fying a Ciocc he already owns. So this might go on the market (a little small for me or I'd keep it).
