Valletta had a different c/n group and production fgures are always quoted seperately. The RAF had some Vikings and they were not grouped witrh the Vallettas.

Autair used them until 1968, I think it was that year Invicta finished with them too and Europe Aero Service into the 1970’s. As far as I know the last one was in France finally retiring in 1974.

I suppose it depended where you were as locally the last Viking was 1963.
