1st pattern M1956 suspenders are identified by the attachment hooks on either end, compared to the 2nd pattern which has clips on the rear side.
Dated pre-1961, but used throughout the war and are more commonly seen than the 2nd pattern.
In very good used condition as seen with all fittings and fixtures present and working except one strip of webbing has bee removed on the right-side strap as seen. Some fraying as seen. Serviceable and ideal for reenactment/display.
