Iv been working on my 1865 Oliver and have noticed alot of yellow paint under the green. This was not unexpected to me as it is really an MM tractor. But it is not a bright yellow. More like a dull yellow primer. I do think that this tractor came off of the assembly line green and was not painted green after the fact like some others I have seen. The yellow that I have found has all been in inconspicuous spots like the inside of the frame rails and the nooks and crannies. The only thing that is an obvious green over yellow is on the hydraulic controls for the remotes. That is a bright yellow and the green is peeling off from it easily. So I guess my question is what color did MM use for a primer? I will get some pics tonight. Thanks
