We have a few class books in the collection for Childress and many have aircraft serial numbers and buzz numbers but sadly they do not come that close to your AT-11 project aircraft 42-37620. Here are the numbers I have identified in the class books we have:
42-37470 (Buzz no. 402)
41-27555
41-27551
42-37212 ? (81)
42-37276
maintenance board with lot of sn’s: 42-37146, 42-37152, 42-37158, 42-37204, 42-37211, 42-37169, 42-37173, 42-37182, 41-9561, 41-9520, 42-37222, 41-9527, 42-37145, 42-37151, 42-37157, 42-37163, 41-9472, 42-37168
42-37214 (55)
42-37162
41-27555 (336)
Since 42-37470 is the latest serial we have and it had a buzz number of 402 I would suspect that your AT-11, 150 aircraft later, would have a higher buzz number than 402 but that is not a certainty. There wasn't much of a correlation between serials and buzz numbers. If you can ever identify your aircraft's buzz number then it will be easier to pick it out in photos.
I was fortunate enough to find the buzz number on my AT-11 project from an accident report. The report had photos of the aircraft showing its from several sides. I see that your AT-11 also has an accident report so maybe the report has photos that will help. If not then it will also give you some names of the pilot and students involved in the accident so you can try and track them down. Maybe you will get lucky and find one of the guys is still alive. I would hurry though, sadly...
Here is what the accident report stats are: Date 440717 Pilots name FAIRBANKS, GERALD D AT-11 42-37620 Location Childress TEXAS
Here is the link to order the report:
http://www.accident-report.com/world/namerica/slist/childress.htmlWe have had about 12 AT-11's come through the shop in one form or another and we have seen and found some interesting markings. One of my mechanics came to me all excited because he found some markings when the light hit it just right. It was the small buzz code on the leading edge of the wing that identified it as Victorville or V-210. With that tidbit of information I was able to find this aircraft pictured in three different Victorville AAF class books. The owner was pretty darn happy too. Too bad it wasn't V-208...

Let us know what you find,
