BLEMISHED: Bulb Horn, Large Oval (Item Code: BULL-2) 6 1/2" bell, 15" length. Brass bulb horn with removable reed and bulb. Uses a bulb with a 5/8 inche fitting. You should expect your brass instruments to have, or develop, an attractive antique patina. However, if you prefer the high shine look we recommend Brasso (TM) as a good polish.
