I have seen posts here on the Tekno brand KZ4, the B-17, the jet fighters, but this one I have in my personal collection and I wanted to share some new photos.
When I was 4 years old in 1968 my aunt bought, in a small local toy shop (shopping mall is still there but the shop is long gone) a SAS Scandinavian Caravelle, OY-KRA by Tekno. It had excellent retracting undercarriage and even the under-fuselage stairway. She remembered it cost $3.98 which was a lot to pay for a die cast toy. I never dreamed there had earlier been such a great prop plane in this series.
There are several other airline colors available for this toy model. I just checked my Piston Engine Airliner Production List and I confirmed SABENA never had a plane with OO-SAB as the registration. The Alitalia plane even has my last name as the registration on the wing but I have never seen a real one for sale.
