Guy said he got them at an estate sale, was told the one ran but may have had pony problem, possibly pinion issue? He hasn't done much of anything with them. Parts machine is 3J7824, possibly running one is 5J9414. Says he's open to offers. Think it's been listed for a month or so, wouldn't be surprised if he'd take $500-750.
