I am a newbie to this forum and have a question or two. I have been seriously considering the restoration of several vintage train engines. My current interest is in the old cast iron AF, Ives, Hafner, ect. O gauge Clockwork (windup) engines, circa 1900 to 1920's. Is there sources out there for replacement parts such as wheels, springs, gears, rails, ect? I have surfed the internet until I'm blurry eyed, with no luck finding a supplier. If there is someone that could steer me in the right direction It would be greatly appreciated.
