Very different larger than normal JD suspensions. Diameter of porcelain is 11.5 inches. Metal cap diameter at base is 17.5 inches. Weight each s exactly 20 lbs. with clevis pin. Short rounded type suspensions petticoats. A JD cap marking that I have never seen before. Large arrow marking on one side of metal cap and large JD logo on the other side . Pin and clevis design. Pin is a large 3/4 inch diameter which is quite unusual. Colors range from a normal JD blue to an almost purple blue. Caps are not the cemented on type. Liquid lead was poured through the cap holes to cement the cap to the porcelain body and then sealed. Very unusual design/construction for a suspension insulator.
