It's certainly not worth the listed price.
I may have heard of O' Malley before, and I remember it being a Chinese stencil brand, maybe with quality control? Regardless, there are far better deals to be had, both used and new.
Its a music shop in Georgia run by a Danny O'Malley. Yes just a stencil horn. Surprising how few horns you have to order for them to put your name on them.... Doug
One of the first things I do when I see a new brand surface is to track down a physical address and plug it into Google Maps to see what sort of establishment they have. The results can be interesting.
My local instrument repair guy bought a few Hunter horns and had his name engraved as the brand name. Portman Music, headquartered in Savannah, sells Chinese horns branded Benjamin.
