I have a couple of horns in progress and both are big horns, huge diameter- 3 and 1/4 to 3 and 1/2" wide at the plug end, but not too long- 14-16" along the curve. This makes for a stout look. I might try to elongate them by adding threaded spouts but I lack a lathe and this would be new ground for me. These will be "supply" or "artillery" horns I guess. The amber/green one can be scrimmed, but the other just has too much black. I'll keep you posted. if you have ideas for these big, "2 pounds of powder" horns, let me know.
