|Above is an advertisement which appeared in a book published in 1899,
Locomotive Up To Date by Charles McShane, a 700-page volume covering
all aspects of locomotive design and use.
The engine Cooke chose to advertise is nearly identical to the engine
Samuel Dunning posed with, right down to the markings of Missouri Pacific
Railway. Except for a cosmetic change to the headlamp, the only apparent
difference is the engine number: Samuel Dunning posed with, and presumably
delivered, engine No. 765. It is entirely possible, of course, that
he subsequently delivered the very engine photographed for Cooke’s advertisement.
