Reading this again has refreshed my memory. Once Braathens had decided the 767 wasn't really their thing, they plugged the resultant shortfall in capacity by ordering another half-dozen or so 737-205s, at the same time offloading their F28s. Interesting that Braathens opted for a tried and tested and thoroughly proven aeroplane, rather than going for the new 737-300. Similarly, their chums at Britannia preferred the 737-200 over the -300 and disposed of their Orion acquisitions after a couple of years or so.
I wonder if the Owners Services 737s, BOSL and OSLA, were actually ordered by Britannia but purchased by OSL as a means of avoiding a potential import tax bill for Britannia ? Or some other complex legal or financial reason ? The aircraft were effectively operated and maintained as if they were Britannia's own -204s, the only difference being a small variance in the customer number, i.e. 2U4. I thought the same about BECH and BECG, although they were -204s.
