Conway's belt.

"Corporal Chad Conway astride his WLA in the streets of a ruined Berlin in 1945. Conway was a member of the 82nd Airborne Division's Military Police Platoon. The saddle of his bike is covered in fur and the handlebar grips are equipped with leather fringes.

The uniform consists of an 'IKE' jacket, wool riding breeches and high leather legging top 'Cavalry' boots. Conway tops off his uniform with a leather kidney belt adorned with a painted 'All American' Divisional sign

Large leather waist or 'kidney' belts (above) were a popular accessory for motorcyclists of the 1940's... It gave the rider support and protection of the lower back while riding the 'hard tail' motorcycles on bad roads for prolonged periods of time. They were not available from the Quartermaster Corps, but many riders acquired them directly from Harley-Davidson dealerships or other sources."
