Not to worry, that tractor is in safe hands now. I didn't read the post on this until about 6:30 this morning and I showed up at his door at 7 am after a 3 mile journey.
Now stated in the ad is that the engine purrs like a kitten and the sheet metal is all straight and original. The only thing that appears to be wrong is that the travel control lever isn't working right--the seller thinks the travel spool is frozen. It has the original muffler which is in good condition and, of course, the glass speaker lenses. It does need a new seat.
The seller has a virtual garden tractor junk yard with MANY tractors of various makes and models. I asked what other Case stuff he might have and found that he had just sold a snowblower last week.

He did have a nice set of rear fenders for a 200 which will soon replace the banged up ones on my otherwise very nice 210. Also got a travel valve, pump and various steel tubes. Didn't see the part about an extra read end but, if he has it, it will come home with the tractor when I go back to load everything up.
I asked how much for the tractor and the extra parts--$140. Tom, did I pay too much?
While there he showed me around a few of his sheds that included lots of things that could follow me home later including at least 3 Onans. We agreed that since it was too cold this morning to dig around looking at everything we would do it next week when the weather warms up a bit. I did notice a nice looking Economy...
