It had the blueish tint when we bought it 25-30 years ago. We have always housed it, kept the oil changed and checked, kept the PS and Hyd topped off. Starts the first time over and runs well, so we haven't messed with the ignition or charging system. It has $1K worth of rubber and the rears are loaded. We mowed our 3 acres of law weekly, May thru Nov. It's 67 years old!
I am holding out for $2-3K.
