Unfortunately, I don't. I snatch Gilson made tractors up when I see them, clean them cosmetically and mechanically, and pass them on to someone who can give it some use. I like the gear drives better than the hydros, for no good reason except for simplicity, I guess.
I do have a later Gilson made Montgomery Wards, I believe a 1979, with a two cylinder vertical crank Briggs. It will be for sale also as soon as I fix the wiring issues.
I have a few parts if you need those. Front axle, early 70's dash panel, PTO/gas tank mounts, and a salvage snow blade mount/front hitch.
If I hear of one for sale, I'll let you know. What are you looking for? Early 70's model, gear drive, horizontal crank?
