This piece was removed from the original International Harvester corn planter, but not because of any problems with the fiberglass! You can see the weathered appearance of the unit from the many years of weather exposure. Glass fibers cover the surface as the resin has eroded away.
The design of this piece included a top lid and a mounting/feed base.
Made entirely of one piece, it has remained structurally sound and durable for its purpose. The harsh fertilizer chemicals and weather conditions have
not affected this piece to the point of failure.
