1950 ACL/SCL Nathan AirChime M5

The 1950 Atlantic Coast Line / Seaboard Coast Line round base Nathan AirChime M5 was the first M series horn in Chris' collection. There is no date stamp as the back of the chambers had previously been machined, but it has "Pat. Pending" bells and power chambers. This one has lots of low end dominance, giving it a great overall sound. This horn was mounted on Eastside Freight locomotive #109 several times.
