Lionel 746-60 Smoke Unit - NOS - The 746-60 smoke unit was Lionel's first attempt to move its large steam engines away from the pill type smoke unit in favor of the liquid smoke fluid that it had begun using in smaller locomotives. The smoke unit shown was developed exclusively the Lionel "J" steamlined locomotive. We do not break down perfectly good locomotives for parts. Our smoke units aren't cheap, as they are new old stock postwar units and they are guaranteed to work as long as you follow Lionel's (or our) guidelines to install them. Ever hear of the statement, "you get what you pay for?" Some of the 746 smoke units have mounting brackets and some do not. We will ship with a bracket until those run out and then ship those smoke units without brackets. You should be able to recover the existing bracket when you change out the smoke unit.
