A pair of Tank Destroyer Forces, Officers Collar insignia. This is a screw back in sterling silver with Gold Plating. This is a proper set with both insignia facing the same direction and also the area by the rear tracks are cut out as required in the uniform regualtions. Many of the reproductions do not have this section cut out, they also face both directions. This came about by mistake in the 1960's by one of the reproduction companies that did not check the real one. This insignia was around only from March 1943 until February 1947.
