I was wondering if anyone knew some history on our 1976 John Deere 3130 registration LBB 187P. My family originally bought it from Mike Richmond's in Malpas 1992/1993. It had come to them from Corbett's also based in Malpas, prior to that it had come from a Heavy Clay Farm or a Heavy Clay Hill Farm. Not sure whereabouts. I've heard between 10 and 20 had been built in this configuration with the duncan cab. I'd never seen one like it until a few years back I dug around online and ended up finding two still kicking about. We still have the tractor, I'm currently part way through restoring it.
