Be careful on this one though. There are several pieces missing here. The front/side engine shields, the stearing wheel cap, Case eagle, some decals, shifter knob, original air cleaner cover. The seat pan is either painted wrong, or replaced incorrectly - I can't tell from the photo. With all those smaller pieces missing in the photo, it's likely that at least some of the throttle/choke and PTO knobs are missing as well.
It does look nice, but if you want an original restoration in your collection, this will still take some effort to get there. I would love to add a 195 to my collection, but $500 isn't all that great of a deal if you consider you'll probably need a parts tractor to do a proper restoration here.
