My latest eBay acquisition was a complete—if well exposed to the elements—motorcycle, a Von Dutch-built and painted 1957 Triumph Tiger 650, to be exact. What to offer for such a piece? Well, a signed Von Dutch gas tank like it has, even in dented, crazed and rusty shape, has to be worth a grand. The timing cover, hand-engraved by Von Dutch with the owner's first name, maybe $500; it'd be more if not for the deterioration. And a numbers-matching pre-unit Triumph T110? Say $1500, even in chopped form. Factor in another $500 for things like the Dutched rear fender.
