Here's my 2-cents: If you want a parade tractor, then generally you want a restoration. The original color of a 9N is battleship gray, not red and medium gray. Inline filters like that are not only not original, they can often be an inhibitor to good gas flow in a gravity-delivery fuel system like the 9N. It came from the factory with three filter screens, two in the sediment bowl and one at the fuel inlet. Also, I'm not a fan of using a rubber fuel line that close to the manifold. Pre-made, metal factory fuel tubes are available. Parts are easy to get in the U.S. but shipping costs make them tougher in Canada. The original carb is easy to rebuild, the aftermarket ones from the "land of almost right" are crap shoots. If you can share the serial number (location shown in pic) I can tell you the year.
If you want a worker, the 9N only has draft control - NO position control. It also does not have live hydraulics - you must engage the PTO to use the lift.
I live in a farming community in central Virginia and that tractor might bring $1,500 US, at best. The early 3000 you showed might bring $5,000 US. The 3000 is a strong utility tractor and I really like them.
