I think that Choppertrain may be right; I haven't found better pictures of X26 that could get every doubt away, but quiz car seems quite little to me to be a 38cv. In 1911 such a power was mostly reserved to limousine and 7 passengers tourer.
Anyway, it's a pleasure to discover among the Rookies someone like Choppertrain who shares with us the excitement of digging in car history.
