I needed to replace a stretched out drive belt from a 6-24147 Lionel sawmill. The belt from Lionel was unavailable. So, I took a 1" traction tire, turned it inside out so the tread pattern was on the inside and installed it onto the motor drive pulley and the pulley that turns the 16mm film strip. And, IT WORKED! So, no need to fret over unavailable drive belts, just substitute an inside out traction tire.
