This is the first variation of the 1082. The model started in 1949 and stayed the same until 1952. Basically the only change then was a new style wheel. The final change came in 1954 and can be seen in the post of Neil's. This lantern is from 1951 (AP 34) and I believe came from the civil defence or phone company here in Denmark. It originally had a red band painted around the base and this can still be seen in the stamping on the tank.
