No expert, but agree it is some kind of costume piece. It does kind of look vaguely reminiscent of the RAF emblem. The screen grab is from Wikipedia. 

Fantastic grouping! Thought it would be worth a share to show a souviner paper from the 323rd Inf on-board the USS Hampton on their way to occupy Japan. Each company wrote a little history, this came from a vet in D Company.

The Vietnam patches and VB-16 patch came in this 1940-50s Boy Scout collection all from one person and found at the flea market    The Boy Scout is also the Vietnam veteran.    

It is nothing I have ever come across so my guess would be costume jewelry.  

The specific items you described belong to the Chest CH-154, which serves as the storage and transit container for the Lamp Assembly LP-14 (also known as the "Signal Lamp" or "Aldis Lamp" kit).   This kit was a standard piece of equipment for U.S. Army and Signal Corps units during World War II and the post-war era, used for secure visual communication via Morse code.   Chest CH-154 Contents List The list of contents printed on the box typically included: 1 Lamp Assembly, Comp. Except Lamp: The primary handheld signaling lamp unit. 1 Connector Cord (20 feet): Used to connect the lamp to a power source. 1 Auxiliary Cord (10 feet): An extension or alternative power lead. 1 Connector Cap (Spare): A replacement protective cap for the electrical connections. 1 Filter, Red (Spare): A snap-on lens for night signaling or specific coded messages. 1 Filter, Green (Spare): A snap-on lens used for alternative signaling or status indication. 10 Lamps, 100 Watt, 110 Volt: High-power bulbs for use with standard AC mains power. 10 Lamps, 50 Watt, 6 Volt: Lower-power bulbs for use with portable 6V batteries or vehicle power.     The Lamp Assembly LP-14 was housed in this rugged wooden or metal chest to protect the glass filters and delicate filaments of the 20 total spare bulbs. The lamp itself featured a trigger mechanism for manual keying of light flashes and could be powered by various sources, including the Battery BA-30 or vehicle outlets, making the dual-voltage bulb selection (110V and 6V) essential for field versatility.   Regarding the chest company itself.     The United States Air Force Air Materiel Command (AMC) was established on March 9, 1946. It was created within the Army Air Forces (AAF) by redesignating the Air Technical Service Command.     In 1961, Air Materiel Command was redesignated Air Force Logistics Command (AFLC).   On July 1, 1992, AFLC and AFSC combined to form Air Force Materiel Command, a single, streamlined organization with an expanded mission. The new command built upon AFLC's expertise in providing worldwide logistics support -- including maintenance, modification and overhaul of weapon systems -- and AFSC's expertise in science, technology, research, development and testing.

The armband belonged to a gaulieter or similar rank political guy, you can see the blue piping on the edges. The mothing might be an issue.
