I'm glad the Balik Scientist program is showing tangible results.

They may have to ask the Air Force or whichever service might have kept the documentation. It would definitely be worth a shot to conduct some
institutional archeology.
As I recall, the Government Arsenal under Director Martir was able to recover the full technical data package (TDP) for the M16A1 from the former LOGCOM archives (along with all the spare parts Elisco left behind). These documents were technically supposed to have been disposed off once Elisco's license was up, but they were conveniently misplaced, much to the benefit of the GA's small arms repair division and rifle production project.
