I'd like to add what I have:
"This car was built by Einar Nilson in 1949.
When his daughter became 18 years old, and was old enough to get a driver license in Sweden, he decided to build her a car. Since he was a competition driver, it was rather natural that it was a sports car.
A chassis from a 1936 Opel P4 got an engine from a Fiat Balilla and a tough 2-seated open aluminium body with
a roomy front (for a large engine) and a sleek end with a spare wheel in a depression. Spoke wheels adds to the impression.
In 1965 a Ford Anglia engine replaced the old one, and in the early 1980s the car got a soft top."
