Input: In a while I will be traveling to Norway for a hiking trip. In between getting from the Oslo Gardermoen airport to Finse, I'll have to get gas cans with a that are UNEF 7/16" threaded, which means they look like this:

Any tips on where to get these? preferably at shops near the airport.

I already found Oslo sportslager, who sell these for sure: http://www.oslosportslager.no/produkt/beaver-power-gas-450-gassboks-25070.aspx

But in case they're out of it, it would be nice to have a backup plan :)

Output:
Locating outdoor / hiking shops which sell gas cans in Oslo?
