Big vehicles, such as buses and trucks, with air brakes frequently vent excess pressure.

Install a big and loud BOV

dont they already make too much noise?

Or install duck calls on the pressure line vents.

One of my books on old cars includes a reproduction of a add form the late 1920s.

Whistles--made out of steel fitted to the end of the exhaust pipe--looks like organ pipes.

Now that would be a hoot.

Did it on my BOV


Hey Art...call a brutha

Stanley Steamers had train whistles that exhaust stem could be blown through. Very cool, and very effective.

Went to a Concours yesterday-- a 1918 Simplex had a small brass trumpet attached to the intake manifold with a cable to the dash.

I talked to the owner and pulling the cable opened a valve and the suction tooted the horn.

It was an option at the time, but there was also a standard klaxon horn.

The earliest entry was a 1897 Bollee cycle-car.

An interesting one was a 1930 Model A Ford Sedan that had completed a Paris to Peking tour earlier in the summer. It had a huge gas tank on the back luggage rack and bigger tires--otherwise stock.
