Who knows this vehicle?

[Wendax]

This will be interesting.

I will give this a one good start:

it is a one-off Eigenbau (self-built) car from Sweden from the early 1950s.

The rest is up to you all out there.

Based on a Swedish Fram-King-Fulda (FKF)?

This is a homemade car built in 1952 by Martin Gagnefur and powered by a 250cc Rex-Villiers engine. It was called "GMG" after Martin and Gullan Gagnefur.

Strangely I have checked "GMG" and "Gagnefur" in advance and the search engine did not show one result.

No more information there.

However this is two points for Wendax, who was first...

[Wendax]

No points for me, please. I didn't know the answer and wasn't even allowed to answer if I would have known it. I just added Rusty Chrome's correct reply into my Eigenbau thread. Sorry for causing confusion. I was just excited that there finally was some information about the builders.

Accepted - TWO POINTS for Rusty Chrome!

I found another photo of this car:

Gullan (the first G in GMG) was Martin Gagnefur's wife. The car was already registered in 1951 and sold in 1953 to musician Sven Palsson from Hälsingborg who sold it four years later. That's where its trace is lost.

This information together with some additional pictures comes from a book I saw today in a book store in Uppsala.
