Its Bergen. B E R G E N. After a town in Norway..... (its a long story).
Bergen. Not BergAn. That would be the wrong spelling....
On the back of my first rucksack, bought for my first go at youth hostelling something over 40 years ago, is a label with the legend
Made in Oslo
It has an external steel tubular frame and is made in grey canvas with leather straps and binding. Some of you other old blighters must remember the ancient 'commando' rucksack of WW2 vintage - I think that was modelled on the 'Bergan' of an earlier age - mine is a transitional model, half way between that basically triangular design and the more modern rectangular climbing sac shape. It's very similar to the 'Brown Best' type that used to be popular long ago.
Presumably Mr Bergan was the Norgie that designed and made the rucksack. They were generally regarded as a very superior type of rucksack when I were a lad and I have no doubt that the tradename is where we get the word 'bergan' meaning a rucksack from.
