Product Description
This is a set of four HO scale vents, for wooden refrigerated rail cars, made per the Edward Posson patent of 1913. Drill out the spot drills and add wires as shown. Wires are not included. Paint the surface shown to represent an inlet screen. The photos show that these tended to rust quite a bit, so consider that. They should be positioned over vents already existing on most models of older refrigerator cars, with the inlets facing inward and the handles to the outside.
