Ex Sou Horns

[MP15NUT]

Im new to this group and i want to know, what horns did SOU use.  The SD50 & SD60's seem to have P5 horns, what units had a P3 horn ???

I found some photos of  SD40's, GP38's, GP38AC's with 3 chime horns. The book lists the GP38 as having a P124. Thats just flipping through '82-94 NS motive Power book.
