My question is as I’m new to the train home community I picked up in Nathan K3HA in beautiful condition recently and I noticed they have ports on the end of the manifold that look like they are for adding on to the horn. Does this mean you can add 2 extra horns and it becomes a K5HA or does it not work that way?
Nobody??
Pics would help, but yes, it sounds like it might be a K5 manifold with block on block offs.
