I noticed a few days ago that BLMA Models has just released Nathan and Leslie brand diesel air horns. The five-chime versions of each manufacturer, were any of these used on Sou./ N&W/NS high hood diesels? These horns look awful nice, i gotta know if these five-chime versions were used on the above mentioned roads. Thanks, berkmeister.
You've been out of the loop! They've been out since October. As to who used what I wish we could help you.
They certainly are. Beautiful workmanship. Or beautiful cast-man-ship. Etch-man-ship? Or whatever. Anyway, they are a very nice product.
The best thing to do is get a picture of the locomotive you are modeling and see which horn matches closest. Sometimes a big trumpet will be in a different location then the photo, but if it is close, no one will notice. Horns get rebuild and repositioned all the time.
