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.
This is my signature. There are many like it, but this one is mine.
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.
