In the hierarchy of Krate bikes this one is not going to be one of the big dollar ones, but there is a market for them.
The expensive ones were the 5 speed, drum braked, rear strut shocked bikes.
Some of the parts will clean up quite well, some will not, such as the rear fender struts, and maybe the handlebars.
The ripped seat will also hurt, they can be recovered, I think even to be made to appear original, but all of this costs dollars.
I would be tempted to do what I did as a young lad for pocket change, "brillo" pad the chrome with lots of water, wash it and see what you have, keeping the water away from the saddle rip. The chain is crusty, but with an oil bath might be serviceable.
I would check ebay via a completed item search, ignore what others are offering, look at what has sold to really understand the market.
I think there is even a Schwinn forum out there on the web with folk who really are enthusiasts about these machines.
