It's called "Swedish Smoker" from Impecco. The pamphlet that came with it states it's imported from Sweden and distributed by Impecco, LTD.
257 Park Ave So. New York 10, NY.
At the time you could buy the smoker for $12.95 and the smoke dust cost $1.95/bag. It says "a special wood powder mixture from Sweden provides the unique smoke flavor." DH got his "prize for $4.
That's it, that all the info we can get. The pamphlet is yellowed and DH's family used it in the 50's through his childhood. I wish had a date but there is none.
