Hand-crafted metal art copper windmill built on old farm mower tooth

Vintage copper and wire windmill, 9 3/4" tall. We love this - the fan blade turns like the real thing, and the entire structure is built on a sickle mower tooth. We're guessing it's probably American made (we couldn't find a marking, but wouldn't believe old mower teeth would be all that common except in farm country) and think it's a great old primitive collectible in the making!
