Just saw the catalog for the next Hollywood memorabilia auction from Profiles in History, and on page 169, lot #767 is Howard Hawks' personal still set of over 100 photos from
Air Force. The pictures will be sold at auction on May 15, 2011 at the Saban Theatre, 8440 Wilshire Boulevard in Beverly Hills. Here's their website:

The auction catalog is available for download - it's a big file, but fun to look at. Is there anyone here who could go to the auction and, if not buy the photos, at least inspect them - and check for more serial numbers? The catalog has a couple shots of
Mary Ann in the listing, but no tail numbers
