Anyone know what a ball park value is for a JD 70LP Gas that runs good and has all original paint. Also my dad had a question about the tanks on the tractor that if they were 'up to code' I really don't know what he means but it might be if the Propane tanks on the tractor are basically like the tanks nowadays. Any insight would be much obliged, thanks all and I'm new to forum I own a 1952 JD A I bought 3 years ago.
