I always thought that the "C" tipped slings in OD-3 were all WWII period and the solid tips in OD-7 post war. However here's a minty "C" tip sling with a 1948 date. Does anyone know the date they changed to the solid tips and who the manufacturer of this sling is? Maybe the manufacturer's using up their stock of "C" tips before switching to the solid tips, Ray
