Thank you for sharing your photos! That looks like a great outfit. The retired seed corn dealer in our area had one mounted on an F-20 but never picked with it. He did donate it to the local museum. I saw one mounted on a Farmall on Youtube but would really like to see one up close and in person.
A few years ago at an auction I tried to buy a McCormick Deering picker with a hopper, didn't bring enough money. I was able to buy a Corn Belt one row corn picker, looks like a early Coop picker.
