what did Oliver use for a certificate of ownership(title) when they sold them? And were they registered anywheres besides state of purchase? 
Does anyone have one that they can scan post here? vintage 1967 era?

I suppose thru time they get lost, not given much thought. Not really needed for road use, but for the dang  tax revenuers i bet, they wanted them.
Anyone here from Pennslvania, that would know what agency would have records for that? Like to get one for mine. that way theres never no question as to who owns it. prior owner say he never got one from who he bought it off of, says he was third owner.
