I bought a 16-4 Dearborn Wood Bros. corn picker. I am thinking it is a 1951 model. The wagon is my Dearborn 21-1 running gear with Anthony flarebox and Century hand pump wagon hoist.
I have both a gray one and a red one. The gray one is complete and does work. I picked about half a wagon load when I first got it about 20 years ago. I haven't picked with it since, but I did have it out this spring and ran it a little bit.
The red one has been sitting in the shed for about that long also. It needs a gathering chain, but otherwise it is complete and I think it would work.
