Date: 1920's. Previously owned by Gary Sloane
The 42H had the tuning slide in the hand slide, not in the crook of the bell. The screw visible in the slide is to adjust the tuning slide; pulling it out by hand would risk damage to the hand slide. The advantage of having the tuning slide in the hand slide is that this allows the entire bell section to be conical, in stead of there being a cylindrical section to allow for the tuning slide. The 42H has a #3 3/4 bore (0.527") and was built between 1925 and 1930. Its former owner describes it as one of the most free blowing horns he has ever played.
