Vintage Elkhart Conn 8-D French Horns remain desirable, but are more often found at horn resellers than at auction. Based on recorded recent sales of similar pieces via online auction sites (as traditional auction comparables are too far outdated to be useful to this appraisal), a Fair Market Value (pre-auction estimate) of this piece would be estimated at $1,400 to $1,800.
