1) WHAT IS A SOURCE OF TRAIN HORNS?
2) DOES ANYONE KNOW OF A MAKER OF 5 CHIME (OR TUBE) STEAM ENGINE WHISTLES? THESE ARE USUALLY 1/2 INCH TUBES WITH A WEDGE CUTOUT NEAR THE BOTTOM WHERE 5 OF THESE ARE FITTED ON A 2 INCH MANIFOLD THAT IS THE ENTRANCE. MACHINE SHOP MADE TO BLOW WITH MOUTH OR SOME ARE THREADED IN THE ID WITH ABOUT A 3/8THS PIPE THREAD FOR AIR PRESSURE. THE ASSEMBLY WOULD BE ABOUT 2 INCH DIAMETER AND A FOOT LONG AND LOOK LIKE 5 MINIATURE ORGAN PIPES STUCK ON A FAT SHORT PIPE.
3) DOES ANYONE KNOW OF A SOURCE FOR EXHAUST WHISTLES? USUALLY 3 OR 4 ORGAN STYLE TUBES ABOUT 1 TO 3 INCH IN DIAMETER AND CAN BE A FOOT TO 4 FEET LONG. I HAVE DRIVEN A HUGE LOCOMOBILE AND A PIERCE ARROW TO CAR SHOWS WITH THESE MARRIED TO AN EXHAUSE CUTOUT VALVE. CAN CAUSE SERIOUS UNVOLUNTARY DEFECATION IF ACTIVATED WHEN PASSING PERSONNEL ON A ROAD
JOE.

Please don't type your messages in ALL CAPS. It looks like YOU'RE SHOUTING.

I saw a number of ads for exhaust whistles through Google, but they were mostly being sold as gags. Their use on cars is regulated in most states (I know about Virginia particularly). You might try eBay for all the items you'd like to find.

For train horns try "5chime"
