Hello all,
Currently researching the various Curtiss Hawks flown on the civil register in the 30's. The most profilic of these were the Hawk flown by Al Williams and Jess Bristow. For this I am looking for information in the way of pictures and info on the colors of these planes. The Hawk flown by Bristow was colored white with red and blue trim. Presumably the early Hawk (befroe it became the famous orange Gulfhawk) was colored red and silver.
The hawk as flown by Bristow:

Anybody know for sure what logo was carried at what time? I have a picture of the right side showing Sohio logo and pictures showing the Esso logo on the left. But never the other way around. The top wing always carried Sohio advertising, also when carrying the Esso logo on the left side of the fuselage.
The Hawk flown by Williams when powered by a Bliss Jupiter:

Colors red and silver? Anybody maybe have a picture showing clearly the Sohio logo carried on the rear fuselage?
The same plane when reengined with a wright cyclone:

Colors presumably still the same, red and silver, but cowling now with scallops. Blue trim line between the two colors? After tis the fuselage would be metalised and the entire aircraft repainted.
The Curtiss Hawk Demonstrator:

This plane would later become the hawk owned by Bristow. Anybody know the color of this plane when it was owned by Curtiss?
Any information and pictures on any of the above planes, as well as other civil Curtiss Hawks of the 30's would be highly appreciated!
Many thank in advance!
