Black elastic strap with metal attachment clips at each end. These were fitted to the Irvin using the small brass 'eyes' sewn onto the rear of the collar. Often referred to as spare goggle straps but were in fact used to help pull the collar into the upright 'stand' position. The elastic is in excellent condition bar minor wear. Both connectors and adjuster slide are equally good. An excellent used example. Remarkably difficult to find. The last decent example we have. Beware of copies! Stock code J22954.
