How much want?

Went walking through the shop today, and the air cleaner for the '81 RX-7 was off and sitting on the bench (carb is being sent out AGAIN because its dumping gas and wont idle), and it gave me an idea.

Use the lid to make a clock! Now I can't buy a new one from Mazda, they're long discontinued, so do I go with a super nice used one, or a dirty old ratty used one, for dat patina?
