Erm.... I was hoping not to have to pay for it, I don't care how rusty it is, it IS made out of foam and I would still like it
I want it so I can learn more about them by opening it up. Having said that, if you are keeping the wheels, its probably not worth my while trying to collect it.
Fair enough with the wheels but bear in mind that mint OEM 5-spokes are rarer than hobby-horse droppings and skanky corroded ones are worth nothing even with tyres on so keep them clean and protected with alloy wax to protect your investment so you can refit them if you sell without your fancy new wheels.
Regards the arch rolling, I'm not sure what you hope to achieve if you roll but don't flare.
