Bill: Just need to do a written request to the AFHRA at Maxwell AFB. They are the primary repository of the records, but NASM has a complete copy as well.
A little info here:

I've got copies of the cards for both of my a/c. The amount of info you will glean from the cards is basic. Where the a/c was accepted from and where it went from there, in a general sense. It will usually only show the umbrella unit that received the a/c and not always the direct unit itself. In the case of my L-5, it delivered to a modification center, then eventually went to Brooks Field and was in an Operational Test unit for much of it's USAAF life. After that, it ended up in a CAP unit til surplussed.
Once you know the umbrella unit, you can then start chasing the units within it, and see which had the L-19's. From there, you jump to unit histories and operational records to see if there is more data and records on missions with that specific aircraft. Be advised, that for any of the unit data that is not already online, you will most likely have to make an appointment and go the AFHRA in person to manually search the records, or order the microfilm and/or fische that cover it.
Once you have the data, it will take a little bit of detective work to decipher it all and get it into a form that will make sense to you.
On writing Maxwell, several of the guys on another board have requested records and the turnaround time is several weeks to a couple of months these days.
