2019 Nathan AirChime
This is the only C5A-CWP in a private collection.
The Nathan AirChime C5A-CWP (C5A-Comes With Plate) was designed to be used on ultra low clearance applications such as the Virginia Railway Express bilevel cars.
I built this horn myself, using 1, 2, and 5 bells from various sources, and the supposed last 3 and 4 bells from Micro Precision. I had Mike Muha of South Bay Horn Works fabricate the manifold block and drill the holes for the horn positions.
I bent all the copper tubing to give the horn an "H5" look. The C5A-CWP comes with stainless steel tubing from the factory.
