Has anybody ever heard of, or used Mobil SHC 639 gear oil? I have a friend who says he has a pail of it he would give me, but I'm having trouble finding too much info on it. I'd like to use it in my 1935 A John Deere transmission and rearend, but I can't find the viscosity anywhere. I did find that it looks to be yellow metal safe, though I don't think there are any brass bushings in the old A transmission anyway.
