quote:Early engines, even many tinplate loco's, used a "smoke light bulb ".
Only three Lionel engines ever came with a smoke bulb: The 1946 version of the 726 Berkshire, the 1946 version of the 2020 turbine, and the 1946 version of the 671 turbine (also the 671R turbine).
Lionel did not make any smoking engines prior to 1946.
The first generation of heater type smoke units were out by 1947.
Lionel offered kits to convert smoke bulb engines to heater type smoke units starting in 1947. Those kits were still available in 1969, perhaps in the Modern era too.
Original Lionel Smoke Bulbs are not that hard to find, but they are expensive. These days, a good reproduction is available from most parts dealers.
Never heard of a Marx engine with a bulb type smoke unit before, I would love to see some photos of the mechanism.
