Pretty Geeky, Mike. I love it!:salute::
But, consider this for the arcane...{eek3}
There's a misprint in the release announcement for IWA-10. It indicated that the Bureau Number for the model that you purchased was BOEING F4B-4 A-
9020. However, your pic above AND the model are both
9026. No reason to be concerned. As I mentioned, the BuNo in the announcement is a TYPO.
Those Bureau Numbers are a tangle in that Navy Aircraft were subject to reassignment at the drop of a hat, either as they were rotated through the O&R cycle, between units, or within the squadron. If a plane was struck or temporarily out of commission, a new one was sent down from the depot. Aircraft could (and were) reassigned within the squadron at the staff's discretion. In other words, the only aspect of the markings that was permanent was the BuNo located on the tail.
Jenkins' challenge was to establish concurrent livery for a section of VF-6 F4B-4, not an easy thing to do in the absence of proper documentation. "Plane Cards" kept for all USN aircraft do not note information other than squadron assignment and dates. Further complicating matters, the Navy did not require that squadron records, logs for instance, be preserved. No, if JJD wanted BuNo's for a section of aircraft, it was gonna have to find pics that brought them altogether. Black leader, or the #10 aircraft was no problem, in that it's so well documented, pictorially. #11 and #12 were going to be the challenge.
Which led the intrepid toy airplane designer (TAD) to a version of this image, the airship hangar at Moffett Field, circa 1935:
Note that I mentioned "a version" of the pic above. As shown here, there's not a great deal of information to be gleaned from the vertical fins of those planes, the place where the bureau numbers were located. However, the Navy does have a very special collection of TIF files that are derived from the original photos. The graphics file in this instance was approximately 6k x 4k and weighed in at a healthy 18 MB! It was from that file that these two images of Black 11 and Black 12 were found:

And that, sir, is the story of how the bureau numbers for these three models were obtained in graphical form, one quite easy, and the other two somewhat less so!:wink2:
Such is the role of photography in historical aircraft research!
