Most of them would have a Nathan K3L. This picture shows a good example ....

From what I can see on the CN's Waukesha Sub., they have the 3 horn cluster, 2 forward, 1 reverse (don't know the technical or brand name), and they are mounted back just before the radiator fans. Not sure if every one is like that.
Try doing a search, there are plenty of pictures of these out there.
