Attempting to help a friend locate info on a 50's era pull behind Allis-Chalmers corn picker(snapper?). The data plate is missing so no serial # or other info is available unless there's one located somewhere else.
What he's looking for is a schematic, detailed drawing, or close-up photos of the head area. He feels as though "something is missing" in the chain area that pulls the corn into the machine but has no idea as to what and was hopeful he could find something detailed enough he can compare. Any help, if possible, greatly appreciated. Posted reply and/or e-mail is fine...thanks.
