You know, Otto, when you posted this I thought it was a nice photo of the prototype that maybe Steinheimer or one of his buddies took in the '50s when they were fooling around with early Kodachrome (ASA=1). I just clicked to enlarge your pic and was blown away in the realization it was a model. Fan-super-tastic! The peeling paint on the fascia is genius. My hat is off, sir!
Devore was a frequent hangout for my railfan clique in the '70s when we were 'fanning Cajon. Of course the station was long gone, but there was this mom-and-pop hamburger stand where Devore Rd. crossed the tracks. Food was good, and we were just a few feet from the tracks so didn't have to miss any action. Wistful memories...
