I hope that I am not posting this in the wrong department!
Recently I received my copy of a the new book, "Pacific Electric Cars - A Pictorial Journey, 1911-1953". On pictures of many of the cars the long air whistle that made such a memorable sound is clearly visible. Usually, it was close to one of the front windows, sometimes just below the edge of the roof. On other cars, the whistle is not visible, at least to me. Which were the other locations were PE "hid" its whistles on some Blimps and other cars?
My interest in the PE and its cars stems from the late 1960's. My first ever record of American train sounds was Stan Kistler's "Sounds of The Last of the Big Red Cars"
I've never heard the word "blimp" used to refer to a street car. With a little net surfing I found a picture of one but it doesn't look very blimp like to me. Perhaps you can clarify a bit.

If your interested please check out Orange Empire Railway Museum in Perris, CA. oerm.org. They have a great collection of operational PE cars including Blimps.
