Going back to this photo of the pits in 1973 again this is the caption from Curt's original source for the photo:
"1973 from left: n°9 Kinnunen_Haldi; n°107T and 107 Pucci-Stekkonig; n°8 Muller-VanLennep "
Given all the other material produced by this person (in Europe) and his obvious knowledge of the event and unbelievable amount of photos with accurate captions, I would say his descriptions of which car is which in this photo is likely to be accurate.
However I wonder if the "n°107T" and "107 Pucci-Stekkonig" are transposed and the real T-Car (which became the race car) is the one sitting next to car #8?
I am not sure what else to make of this.............
