Miller,

Your memory is amazing... It was introduced in 1938. They sold a bolt action and a repeater. About 9 years later Mossberg announced it was going to the enter the market with the Targo. They made the M 42TR smoothbore. There a contraption that fitted on the muzzle that would toss the Targo clays. Though I don't know when or if the M42TR was ever actually sold.
