This tractor was discussed recently here.
The quality of the "restoration" is in doubt because the side panels have been installed upside down, the exhaust is wrong, it has "130" decals on the sides and the hydraulic lines appear to have been left unpainted.
Yes...small things......hair splitting perhaps..... but if you use the word "restored" then you need to be able to back it up.
What you do, when restoring anything, is either correct or incorrect. If it's 100 percent correct, then you have the right to demand the big bucks. If it's incorrect, no one is going to pay you that kind of money for a tractor they now have to take apart in order to fix your mistakes.
