ARVN / Vietnamese Air Force Lt. General Bullion Slipon Shoulder Rank. Black velvet slip-on boards. On each are three silver bullion embroidered star and a gold bullion winged star. These have been used. Doing reseach Ky was only a two star, don't know if he ever self promoted himseld to a three star. This is the only set of these I have ever seen and I collect VNAF insignia. Just received a message from Francois Milliard that the three star boards belonged to Trần Văn Minh was a Three Star VNAF General. He died in California. Thanks NTS.
