Hi folks, 

I'm trying to decide if I want a free Pettibone Speed Swing. "Ran when parked" so it's a mystery as to actual condition. A friend sent me some photos, but it's a ways away from me so getting it here will cost some bucks.

It's certainly an interesting piece of equipment but I can find little historical information on line such as year introduced and the evolution of models. I'm mostly interested in pre-sixties equipment but really know nothing about these.

Thanks for your help!

Mike
