1930 / 31 Used  Ford Model A Quail Thermostat Locking Radiator Cap. This cap fits well and the gaskets are good,
there is some pitting and the glass thermostat needs replaced. There are no repairs and it shows well and it may polish up some more. It can be used as is or could be restored. It has very nice detail on its wings, different than today's reproductions and it opens as it should, the hinge is not loose or worn out. . See photos for details.
