4-4-0 SLSF 104 4-4-0 SLSF 104. I adjusted the contrast of this shot to bring out the engineer and brakeman or conductor. It appears the engineer is oiling a rod. It has a wooden cab and notice the metal rod brace holding the cab down to the frame. Also the locomotive appears to be very clean and the paint oiled down. Date and location unknown. From my Post Card collection.
