sfshredder,
The clock housing is a relatively rare item. It was a Chevrolet accessory available for any model 1954/55-1st Chevrolet truck. It held a hand-wind clock (with light bulb) that was also used on 1953/54 Chevrolet cars.
You could sell it first-come, first-served; or, sell it by coin toss; or, sell it by lottery; or, just give it way; or, offer to trade it for somerthing for your truck; or, get the best price by selling it on eBay. Or, you could save it - just in case you ever get a 1954 truck.
