I was in contact with Miabach Tractor last week and they said that the planter is either a 1962 or 1972/4. But the planter in the picture that AB posted is what our planter is exactly.

I know the planter frame was/is painted in a Green, and the press wheels was/is painted in a white, and the back hopper lids was painted white before I sanded and primed it again.
