No. The bodywork comes from a different country than the chassis.
This car is a bit of a problem to me.
I had gathered a small brochure of it last year that has shown some more details.
Now I cannot find this brochure any more.
And my HDD had a problem in the week I´ve posted this one, so there´s no scan any more, too.
As far as I can remember this conversion was planned to be built in a small series.
A new pre-war style body (as can be seen in the puzzle pic) on a common basis car...
I cannot find any details to be honest, but I can remember the chassis.
Maybe we can find out together...
