BLEMISHED: Bulb Taxi Horn, Circular (Item Code: BULH-2) 2 3/4" BELL, 14" length. Solid brass with removable rubber bulb and metal reed. Great honk. 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.
