Fascinated by Gears and Pulleys

Lately I've been fascinated by gears and pulleys.  For example, if you look online at a store like Restoration Hardware, there are reproduction gears and pulleys for sale for about 120 dollars.  You can look on Etsy and find a real gear or pulley, not a fake, for under 40 dollars.  Not everyone goes for this kind of item, but I think its pretty good for someone with a mechanical or rugged-type background.  I recently bought one from a seller for pretty cheap thinking I would display it somewhere, but decided I would rather resell it after finding another Pulley I liked even more.  I'm selling the one below for about 35 dollars, very cheap compared to most others online.  Here's a picture of it:
