Can any of you identify this planter for me and give me some idea of how old it is? and possibly more importantly were they any good? Over here in Europe these are rare machines, I have never seen one quite like it. Its for sale and its got no numbers on it and I want to know what I am dealing with before driving a couple of hours away to see it. The guy selling it doesn't seem to know much about it. I need to plant corn and sunflowers. Its a "mechanical" not pneumatic, if that makes sense (I am not sure of the correct terminology for the USA version of the english language! I am an Englishman in France). Thanks for you help.
