"A little bit earlier and smaller" Hmmmmm! I have a couple of choices from the same year, but have photographs of neither. One is a six cylinder, and one is a four, with the four cylinder being slightly larger. Because the photograph I have of the S14 (14/60 PS) looks very similar to the puzzle car, I'll go with the six, and say: 1926 Elite S10 (10/50 PS) Pullman Limousine.
