First thing is to get the FAA data if it ever had an N number. Takes a couple of minuets to order the CD with all the records on it that the feds have and it's only a few bucks. Probably will take several weeks as it's file is most likely in the archives.
Second is order the military record. Rob M. or any of the guys that deal with NavAir history can point you to the right location to get the Navy records. These records will probably only be very general, in giving unit assignments and dates, but from there you can delve into the unit history and try and come up with more data. One good research site is
www.vpnavy.com .
I've got the military records on my Fairchild and Stinson, and the data is pretty sparse, but gives me some direction in doing further info chasing.
Hope this helps..
BTW....Scott, the contact info for AAC/AAF/AF and Navy aircraft records might be worth posting as a stickie...
