Just returned a tag I recently found with my metal detector on base. Gave it to a thankful Avionics Technician at Seymour Johnson AFB. It says, "Attack Transmitter for F-15", with unique, specific Manufacture number. I found it in front of Base Ops, about 3 inches down. He was suprised and thankful. He said he can look in their records and find out info on the equipment piece. History.
