Hello,

I have the older A47MLR rotor valve section for the artisan Bach trombone. I love this valve I would just like something a little more open and free blowing.

I had my associate at the shop brush off MLR's initials and he even styled the rotor cap to look pretty cool! The section was cleaned and had work done yesterday! So its good to go.

I'm looking for an A47I (Infinity Valve) for anyone who may want to trade theirs for mine. Please let me know!
