I have that picture with a watermark that has no clue for the name of the car. The name i have is Nobuyuki Kosaka, but i think he is the photographer. The year (of the picture or built of the car) is 1968.
Hello Mr Scharroo and nice to see you here!
I had the car as a home-built special built by Nobuyuki Kosaka in 1968 so I'm going to give you the point for that..
Below shows what was written on the reverse of the photo used for this puzzle, from which you can see that the car was indeed built by Mr Nobuyuki Kosaka and what's more it has a name, which I have included in the heading!
Well done on doubling your points tally!
