First year Superposeds imported to North America had the Ogden, Utah and St Louis, Mo. address. After that, they just had the St Louis, Missouri address. At some time in the 1950s or 60s, they added Montreal, P.Q. to the St Louis, Mo. address. Between my 1970 28-gauge and my 1972 BROADway Trap, the address changed to Morgan, Utah and Montreal, P.Q.
