Chris, Tone, nothing much gets past you guys.
All I know is the actual plane judging from the registration was a Vickers Viking, crashed in 1946, the same year it was delivered.
The toy then should be post war but this seems illogical as production must have been simultaneous with the beginning of their die cast aircraft , the lovely Danish SAI Kramme & Zeuthen KZ.4. I have a sliver and red one with the same registration.
Here are some examples of the KZ 4.

Tekno did a very nice line of tin Fire equipment which for some reason interested me many years ago and I acquired some of the items.
