Gleaner fan, your right. It may have been an improvement put on the later serial numbered machines. Although they had the new improvement of the upper pipe on the feeder house for hook-up, the older headers still had the older style 2 pin (one upper and one lower) attachment. So, until you traded up headers or attached the adjustable cast iron hooks on your old headers, you could attach headers the old way. My 1968 gleaner EIII combine serial number 27674 has both setups on it and the 1967 brochure for the EIII shows it that way for hooking up to an older header that still has the 2 pin brackets on it.
