There is a chance that 110113 had two different noses. It is said that 3 T26's were built by Franay, but one of those was a convertible. That leaves 110113 and 110123, with 110123 having many styling differences (nose, side, etc.). The puzzle car only seems to differ from 110113 in the front.
I wish I had access to the $650 Talbot-Lago Grand Sport Book. That would probably be able to solve this one.
What information are you looking for to call this puzzle solved? A year?
