My guess would be that ebay is your best bet for selling an unusual item like that. You might want to figure out your shipping costs to Europe and Asia to cast as wide a net as possible. There are considerably fewer people looking for components of that age as compared to Nuovo Record for example. In your favor is the fact that there are very few available.
