Stitched onto the peak is an insignia consisting of a dark navy blue rayon backer bearing a machine-embroidered golden-yellow Kriegsmarine eagle clutching a mobile swastika, measuring 70 mm (w) x 25 mm (h). Directly below the eagle, cap bears an additional insignia consisting of a machine-embroidered tri-colour cockade on a dark navy blue rayon backer, measuring 32 mm (w) x 32 mm (h). Notably, the left side of the side wall is embroidered with an Olympic ring decoration executed in silvered bronze with multi-coloured enamels, measuring 45 mm (w) x 20 mm (h), as worn by the crewmen of approximately 23 U-Boats who entered service during the year of the 1936 Berlin Olympics. The reverse of the badge is maker marked with the logo of Carl Poellath, Schrobenhausen. The interior of the cap is fully encompassed by a multi-piece black rayon liner, with a white ink size mark of “57” visible on the right. The cap measures approximately 29 cm (l) x 13 cm (h) when folded on a flat surface. Moderate fatigue is visible to the cockade, but the cap demonstrates no other notable damage or wear and is a scarce example in extremely fine condition.
