fearless,
As it turns out, I have a subscription to Scribd, and an e-copy of that book is available on that site. I took a look for you, and the only photo of BBD is the same photo you had posted of Landers exiting (entering?) the cockpit with the two chiefs on either side. I downloaded copies of that photo from your post, from the book, and the highest resolution copy I could find on the web. I played with all three in some photo editing software, and I wasn't able to distinguish a yellow outline around the squadron code markings. I could definitely see the yellow block on the canopy frame, but I could not make out any other yellow markings.
I was able to find a copy of the original war-time slide where the photo in question was taken from. (You can see it here: https://www.flickr.com/photos/dougsheley/4313620987/sizes/l/) In my opinion, it's pretty clear from the slide that the squadron markings are not outlined in yellow. Also, there are some very informatiive notes posted by a viewer that might be useful.
I hope this is all helpful. I plan on building a BBD one day, and all this info will assuredly help me with mine.
Good luck!
