By the looks of it, it is probably too tall for me. What size is it?
Ah, yes.. I too had a 1982 Specialized Expedition. Bought new in '82. I took my first tour on it. A Jefferson bus from KCMO to Denver. Denver to Colorado Springs to Manitou Springs back to Kansas City. 8 days, 650 miles. What an awesome bike.
Completely loaded for another tour, someone kicked in my back door of my house one night and rode off with it. By then, Specialized quit making them. I couldn't find another one. But I always keep my eye open! This bike rivaled the infamous Trek 720. I think the write-ups may have even favored the Expedition! Do you have the headlight and bottom bracket generator?
What I see in your pics is a very pristine touring bike. It will make someone a very sweet ride,, indeed.
