Heating elements

I know that Lionel makes a heating element (27 ohms,5-16 volts). MTH has a element (16 ohms, 5-10 volts. Can anyone tell me where I can find a heating elemt that is 19-20 ohms, 5-16 volts? What I am trying to find out is where I can find these types of resistors and if they come in different ohm and voltage.

Thanks everyone

Lionel used to list a 22 ohm for the scout smoke units with can motors. don’t recall the number off hand but it shows in thier parts books.

Thanks
