I just picked up one of these old gems; no tender or trailing truck. It was absolutely filthy, encrusted with lint,hair and dirt. No way would it run. I shot some contact cleaner at the motor and hooked it up; it sputtered a bit,then took off and ran just as nice as could be. Man, you gotta love these old models! So impressive that this 60 year old "toy' was so well designed and rugged.
The date stamped inside the boiler is "May 1949".I see by my online research that the "AC" model appeared with two types of trailing trucks: which one would be right for this '49 model?
