Painted the parts for the Oil Cooler Box Assembly with an engine enamel but probably did not need to do this because most of them will be covered by other parts. Riveted the FF-1215 Oil Cooler Spacers to the FF-1212 Oil Cooler Frame and riveted the Frame to the F-1214 Oil Cooler Faceplate to make the Oil Cooler Box Assembly. Painted the F-1204A Cooler Box Face, the F-1204B & C Cooler Box Ribs and the F-1209 Seal Face.
