Does anyone have a suggestion about finding a loudspeaker horn in HO scale? (Actually, I need three. . . ) I’m specifically looking to find the same sort of loudspeaker horn used atop the rear of the presidential railroad car Ferdinand Magellan. Any info about such an item or a reasonable stand-in, or how one might scratchbuild one will be much appreciated!
You may want to look at these, I’m not sure if they will work for you. It took me forever to find them a couple months ago when I looked for a MILW & SOO project. (They look look a bit better than the picture.)
