Third Reich Gau Main Franken Badge-This is what is known as the Gau Main Franken Oath of Allegiance Badge. It is solid metal, nickel finished, slightly convex round measuring 1 1/2" in diameter. It features a raised hand with two fingers in the air superimposed over a mobile swastika. The script around the perimeter reads "Treueschwer 25.2.1934, Gau Main Franken". The reverse has a vertical pin that functions as intended. Excellent!
