I have an old (1946) 726 Lionel Berkshire in fairly good condition. The smoke unit on it was the early design that used a large smoke bulb as the generator element. This smoke unit was the original design that does not work with the current day smoke pills or fluids. Lionel used Ammonium Nitrate pills in it to produce smoke. While it did produce smoke it was found that this chemical was not only very corrosive it is highly flammable. It is still available but DO NOT USE under any circumstance Ammonium Nitrate. It is hazardous, dangerous and can destroy your equipment if not yourself. Having said that I am looking for a way to change over to a modern smoke generator or find a commercially made smoke fluid that will work in the early 726 smoke mechanism. Anyone have any ideas that might work?
