I recently bought a 1959 841 tractor. When I purchased it, the previous owner pointed out gold paint on the rear end under the red and blue paint. He also stated there was some on the engine also. I moved it in the shop to start working on it last week and was surprised to find gold paint on the transmission housing also. We both assumed it was a selecto speed tractor originally and had the transmission swapped out, because I never heard of a 841 gold demonstrator. As I worked on the tractor this week I found gold paint everywhere. Also it has the brake locks, which weren't put on the selecto speed rear ends as the transmission has park, and alot of work to put on. Were there any other gold demonstrators that weren't selecto speed models? The neat thing about this one is that it has the elenco four wheel drive system. Trying to decide if we should paint it gold if it truly was a demonstrator originally.
