While looking for information on the 109th Observation Squadron I came across this link. It is the location of all AAF Squadrons and type aircraft on 12-07-1941. My O-58 was with the 109th and they were in La. on that date. You can scan down the list and see where all of the O-59 aircraft were as well.
