If you start in 1912- when the Model 1912 first came out in 20 gauge- 2.5" chambers, 25" plain barrel- retailing at $25.00, and go to late 1964 when WRA dropped the Model 12- about 1,900,000 ball figure from production in all grades, gauges and variations, including Custom Shop M12's-- this does NOT include the M42- the red-haired step-brother of the M12, in the midget bore- .410-- OK for skeet, expert shots only, but as worthless as tits on a rain-barrel for clean kills on upland game birds like pheasants and grouse and Hungarian partridge--maybe OK for quail and woodcock, but I am not sure even about that.
