Thanks for the Benelux manual, too! That may prove to be a valuable resource. In fact... do you think you do a better scan of it some time?
I'll do a real scan of the docs this week-end some time and post or e-mail them to anyone who's interested. Those are just digital pics I snapped on the dining room table.
I haven't had a chance to really tear into the Benelux parts yet, I plan on getting some cleaning time in this evening. I'm a little nervous about pulling it all apart, hopefully I'll get it all back together again. I think I've decided to do what you recommended and leave this as original as possible. The saddle will obviously need to be replaced, as it's unridable as is. I'm thinking of trying to find a Brooks B-72, since a lot of the old Schwinn's had them, I can't off the top of my head remember the saddle brand name that's on it now (I'm at work, damn jobs!) but it's not Brooks.
I doubt this bike will ever be a daily rider, it weighs too damn much! But, I will enjoy the occasional spins down to the Farmer's Market and the discussions sure to come up at the bike valet!
Thanks to eveyone for their comments so far, I'll post the progress, slow as it's sure to be.
Any suggestions on getting the cables working smoothly? They're pretty unique looking (to me) and I'm not sure that modern cables are going to work (for the brakes, anyway, the shifters should be replaceable). I really like the idea of keeping (or replacing with the same) the white cable housings, as they're not anything like any of the more modern cables. I'll snap some photos of what I mean when I get home.
