One of the local collectors in our area has a Mow Bike similar to it but I think his might be even older. It was on diplay the last time I say it and it's 100% original!
He's got some of the wildest toys I've ever seen. I'm hoping that someday I can get up to his Mall and take some pics. Yes I said mall as in a building with many stores! He has all kind of crap on display. He just recently bought an Evenrude HeliBout. It's one of only three and is a combination helicopter/speed boat!
