Can anyone steer me to prototype and/or HO modeling tips on western railroad slide detectors, preferably transition era? 

I’m repowering and installing DCC sound in an LMB McKeen Car and I’d like to finish it to appear as in the photo on page 244 of Mac Gregor’s South Pacific Coast sitting in front of the Ben Lomond depot circa 1912. Can anyone guide me to realistic modeling paint colors suitable for airbrushing? I have it on good authority fron Fred at the Pasadena Whistle Stop that the body was Pullman Green. The roof and the trucks are in question.
