Early Model International Harvester Type C Duplex Planter Hopper Lid.
Will ONLY fit early model duplex seed hoppers.
Early model lids had the "IHC" Logo in the center and had two hinges on the rear and a locking tab on the front. Those were used on duplex planter attachments produced in the late 1930's and early 1940's.
Later model duplex planter lids had a single tab on each side of the hopper lid to allow it to lock in place.
EARLY and LATE model planter lids will NOT interchange.
