Bob - what got me thinking about this was a picture of the Kirkham street car that lacks the
oil cooler intake. I know that doesn't mean anything definitive about the original cars so I started looking at some other pictures of what I think are original cars.
The Kirkham picture is obvious.
I had this picture of a white car on file and it appears to be missing the
oil cooler.
I found CSX3329B and CSX3342E car photos on Cobra Photo Gallery that are not shot very low either - but appear to show a car without the
oil cooler intake.
It's very difficult to tell from the photos in the Gallery if they have the oil cooler scoop or not. The dark colors and nudge bar may hide it if the photo isn't shot from a low angle.
I was just curious if this might be an option.
