The original image I was working from was quite large and I did not what to post that large of an image. I cropped out the area in question so you all can get the "full-size" view. The area I'm looking at is around the cowl latch. The shadow would certainly have to cross the latch. Also, if the prop where casting a shadow, it would cross into the white band and you would see some contrast in the white.
In support of Guppy there is a line going over the top on the anti-glare panel. I took this line to be a seam. But it is possible that applying the red over the glare panel is causing the difference in color near the latch. The red paint could be slightly transparent, or the underling glare panel is causing a difference in texture.
I don't know anything about the process when a new aircraft arrived at a base. The red band and squadron badge might have been applied before delivery and not having the red noseband go over the top was an error. So the photo may have been taken 5 minutes before the guy with the red paint and spay gun showed up to fix the error. Maybe the original paint job was correct and the group switched to the full nosebands sometime after the photo. The 57th flew with a mixed bag of razorbacks and bubble tops from the beginning as far as I know. So having a photo of a razorback with a complete noseband is not necessarily proof that the group always had complete nosebands.
I post images to get a peer review as Fencer pointed out. I don't have any problems adding the red over the top even if the conclusion is the red did not go over the top in the photo. I'm sure it would have been added at some point (and it would also help hide the skin stretching in that area). So what do you all think? Go ahead and apply the red over the top?
All opinions matter – whether they count our not is a different story. I appreciate the input.
