So here's the skinny. I recently picked up this horn on eBay for ~$200. My intent was to fix her up, relacquer and make her nice and shiny, and turn her around locally for a decent profit. It's about 85-90% lacquer, but has scratches. Anyway, I fired it up with my own mouth piece (the one that came with it is chipped) and nothing below a G would play properly. I tinkered and tweaked, and eventually removed a piece of too thick cork on the octave mechanism. MAN!!! Does this mother BLOW! Here is my dilemma, I can't bear to relacquer this thing and risk damaging this beautiful tone/resonance that this thing has. I literally just started blowing a George Adams song I don't even know (More Flowers from the album Earth Beams). What I'm wondering is what is the story of Martin-Busine. All I've found is that it may be an italian intermediate horn. Feel free to set me straight and offer your $.02 on my current relacquering dilemma. I'm goin' to play some more George!!!!!!
