Decorator Bugles set of 2 Brass slightly Different

These bugles are slightly different but go together well if that is desired. The one on the right is smaller in height but the tubing is larger in diameter and it has a larger mouthpiece. It also has a slightly darker patina and is reinforced with built-in brass couplings (3 in all). And the circle in that one is slightly larger 5 3/4” compared to 5” inner diameters. The taller one is 8 3/4” compared to the “stockier” one at 8”. The taller one has a “Made in Taiwan” sticker in the bell. I assume these are for decor only!! Thanks for looking!
