After a thorough cleaning and a Tom Aker gasket/donut replacement kit. This is the re recording of ebay item # 290744513769. Or for the real world. A ex CSX Leslie RS5T. Its date stamped 1969 with a tag saying S-5T-F with .125 orifice. The horn was obviously upgraded with RS power chambers at some point in its life. Some of the bells have yellow paint down the throat. Enjoy the updated sounds.
