MyothersanM1:
Understood on the tank and valve units. The metering valve is a conventional Graham White engineers valve with the brass handle. Most older locomotives had the valves mounted against either the roof or front wall of the cabs and used a "J" shaped valve handle with an eye, so that the rope could be run through a pulley and down to an eye bolt on top of the control(ler) stand. Often we had two (2) horns with valves and cords, one for "Town" use, softer then a road horn; and then the "Road" horn, usually much louder, more strident, often with more notes to form a 3, 5, or 6 chime note.
The KS-1 by Nathan that I remarked to you earlier is a unit with one note, cast aluminum body and diaphragm cover, extremely loud and very harsh, as they were either used on first generation units in pairs (one facing forward, one facing rearward) or as only one horn on a switcher, usually mounted to the front cab wall or on top of the hood. Westinghouse and the Leslie Company made similar units under different names, I bought mine new in 1974 for about $60.00, when a new Westinghouse Trombone ran about $40.00 in Brass. WABCO will still manufacture the Trombone or Clarion whistles (probably in brass), but I will bet the price has gone up considerably. That's the nice thing about WABCO, they will make anything new that they ever made in the catalogs, you just pay highly for it.
Have a Great Morning!
