My Bialaddin 315, Dec 1959. This one has the small and large dots on the bottom so I could date it. Note the next photo. This lantern was purchased from a UK dealer but note the distributor's name and location. I know Anderson was a dealer here in the States but it struck me as odd it found it's way to the other side of the pond. The dealer would have placed this sticker on the lantern, not W&B. Anyone have any thoughts on this?
