Looks very similar to my 86-87 Specialized Expedition. I believe both frames are Ishiwata 022. The Exp. came with Suntour Montech derails, but according to an article by S. Brown, the Suntour rear D had a bad habit of major failure and I've noticed that many 80's bikes with Suntour Ds often had the rear D upgraded. Saw the pic of the Shimano Deore, don't know if that maybe a similar upgrade for those who demand originality. I contacted a guy in the CHicago area who was asking a firm $800 for his 84 Expedition and was receiving serious inquiries. I believe it was Sheldon Brown who wrote that the top 3 off-the-shelf touring bikes of all times were the Trek 520, the Expedition, and the Miyata 1000. I don't know about the market inwhich you live, but in the major cities along the West Coast I wouldn't be suprised for it to sell between $600-800.
