Balwin VO 1000 Locomotive

[Cincykid]

I have the Stewart HO Balwin VO 1000, Pennsylvania RR version. Where did the PRR place the diesel horn on this type of locomotive? I have viewed several pictures of the prototype and none show the horn.

It's gotta be under something! I looked at all the pictures of VO1000's in "Pennsy Power II" and Don Ball's "PRR, the 40's and 50's" and I don't see a horn anywhere either! The bell is under the walkway, maybe the horn is, too.
