584477 is the coil for a 1955 model. I think the same coil was used on most systems of that type. Take yours to a local dealer and compare them.

You can get them at the NAPA stores around here, they will have an after market brand called sierra. 18-5181 should be the number you need.

Well thank you very much. i got the motor running today. Before i looked for the coils i made sure all connections were good. found out the reason one of my spark plugs didn't fire was because the wire going from the magneto to the plug had a poor connection. just cut about a half inch off and reconnected. Put it in a barrel and it fired right up.

Yep, the same coil will work in your TN as the JW model.
