This is estimated to have been made in 1920 and has slides to adjust from high pitch to low pitch. The horn is in great shape from what I can see and it's rather beautiful looking. It has gold wash inside the bell. Hard case is included and looks serviceable given its age. Proceeds from the sale benefit the River City Youth Band, a 501(c)(3). Starting bid is $199. (Many more photos on the listing.) (UPDATED now with new URL. He has it set now as a bid-only auction starting at 199)
SOLD FOR $207.49
