<BR>Hello Bill,<BR>
<BR>
The horn on the 6175 (at least as delivered) would be a Leslie RS5T. Three chimes faced the long hood end as this unit was configured long hood forward. These horns were the predominant standard on N&W EMD Diesels from the GP9's thru the SD50S's. The only exception on the EMD's I can think of would be the split horns on the as-delivered High Hood GP30's. They were converted later to the RS5T.<BR>
<BR>
If you're doing this research in pursuit of a modeling project Details West offers the parts as #191 in HO Scale. If it is for another scale, maybe some O or N-scalers can chime into the discussion (pun intended).<BR>
<BR>
If you would like to hear the "voice" of the Leslie RS5T there are some videos of nicely restored Leslie RS5T's demonstrated on Youtube.com at various horn honking events. Go on youtube and search under N&W Leslie RS5T.<BR>
<BR>
Thank Ya'n Out,<BR>
