If someone is trying to restore a period correct after market A/C unit, it might be useful to them. You can try putting it up in the "for sale" section to see if anyone bites. Stranger things have happened. I suspect though, that this part is probably more likely to be a fugitive from the trash can. Anyone doing a serious restoration of a vehicle will usually get rid of after market air. If you have the complete unit, someone might want to install after market air on a driver quality car.
