This little unit is a mystery. Nice re-engining job, left it with some dignity and really nice tall stack but I'm not sure of its origins. It was apparently 703 somewhere.

PT 704 is ex-Yreka Western 604, exx-Portland Terminal 31, nee-Northern Pacific Terminal Co. (Portland) 31 (still in numberboards). Kodacolor X, Leica M-3, Summicron 50mm f2
