There were approximately 100,000 New Services manufactured from 1914 thru 1917 and most were chambered in .455.
Most were British and Canadian orders, probably more than 1/2 were "commercial sales".
During the same period approx 79,000 S&W First ("Triple Lock") and Second Model Hand Ejectors .455s were manufactured with probably a higher ratio to Gov't sales.
So roughly 160-180,000 Colt and S&W .455s into the storm.
