You'd probably be able to sell it's individual components for more money separately than you'd get for the whole thing as a roller. Spindles, axle, wishbones, banjo rear, drums, wheels all bring pretty good money and there's demand. If you don't need it, price the stuff fair and post in the classifieds here.
I guess I should've asked if you were looking to buy one or sell one you already had... Since you also posted earlier that you are looking to start building a traditional rod, you must be lookin to buy one. It's worth whatever you are willing to pay. Lots of good parts there...
