All Kamplite stuff is 1950s. Queen Stove were taken over by King Seeley around the mid 1950s so this will date from before that. Call it 1950 to 1955 and you will be near enough. ::Niel::
Hi. This lantern was introduced in 1954. Confirmed via advertising and a new-product review. AGM to 1950. AGM Div. of Queen Stove Works: 1950-1957. Queen Products Div. of King-Seeley: 1957-1960. King-Seeley/Thermos 1960. I nailed down all the merger dates last year. Short version: 1954-1957... but - we can nail it down further as the -1 model with the old style pump. The pump was changed around 1955, so this one is 1954-1955 (maybe into '56). The next model with the cheaper pump would be the -11 model. DR
