I know the USAF Historical Research Agency at Maxwell AFB, Alabama, keeps official forms (cards) documenting every USAF airplane's assignment history and, later, disposition once it is stricken from operational status. A few years ago I successfully requested a copy of a card documenting a particular B-58 Hustler, and that card contained a great deal of useful information. Unfortunately, I no longer recall the numerical designation of the form/card or what it is called. Can anyone help with the form's name/numerical designation? Does anyone know how far back those records go, i.e. WWII, Korea, etc? I'm trying to find data on a WWII-era Curtiss P-40K and was hoping I could request documentation from the HRA at Maxwell.
