Hi Ryan,
Yes there are of photos out there but most researchers were more interested in a persons or unit combat record so most of the training photos where just lightly touch on and then the editor would cut off the base photographers’ margins’ notes so that you can’t tell where photo is taken.
A good source of photos are field “class books” that are done like a high school year book but they are limited to Training Command fields. The number Air Force fields are like Brownwood seen to be limited to crew or personal photos like you have posted on your friend or crash photos but most of them are poor reproductions from microfilm.
Just to add to the frustration here is a L-5 in markings very close to what you have posted, but I can’t make I.D. it for sure.
The L-5 has to be from a base, say may be a 100 miles or so from the Convair factory at Ft. Worth, TX where the B-32 where built which could be possibly 4 or 5 fields, including Brownwood.
