The pick-up looks American to me.
That is what I thought, but it is RHD.
I don't think it's American. Filler appears to be on nearside, that makes me think it's origin is a RHD country. Unless there's one on both sides, of course
I wonder if it's Scandinavian, RHD era? Volvo TL/Scania-Vabis had some vertical barred grilles early on. Can't help thinking it looks British 50s style front end though, with the headlights low in the grille.
Somebody must know the answer!
