Conn 8H Artist Symphony
Date: 1962. Owner unknown.
Notice the 8½" "red brass" bell. This is not the same as "coprion", which is 100% Copper. I have been told that red brass is about 90% Copper, 10% zinc. "Rose brass" or "Gold brass" is 85% copper, 15% zinc so I understand from the same source. "Regular" brass, also known as "yellow" brass or "cartridge" brass is about 70% copper and 30% zinc. The 8H is essentially the same as the 88H, except that it doesn't have the F rotary attachment. The 8H was produced from 1954 through at least 1974 and has a #4½ Bore (0.547").
What Conn said in 1955:
Here's Conn's largest bore tenor trombone... preferred by top symphony and concert band trombonists. Has famous Conn "Airfloat" slides
with lightweight, integrally-drawn one-piece stockings... so smooth it's as if they're "floating on air." Outside slides made of special
Conn formula brass alloy. Has ½" red brass bell, weighs 3 lbs. 15 oz., is 45½" long. Comes in handsome Stratoliner
plush lined case, with mouthpiece and music lyre.
Highly polished brass, beautifully nickel trimmed, clear lacquered.
What Conn said in 1959:
Large bore gives "large sound" with ease of control and great flexibility. More and more symphony and concert artists are
adopting this trombone as the "standard" for ultimate performance. Features include: 8½" red brass bell, smooth airfloat
Crysteel slides, acoustical balance of taper, Lustre-Conn finish.
What Conn said in 1966:
Two [8H and 88H] of the most widely used trombones in the symphonic field. Red brass bell delivers darker sound and greater
projection. Bore size .547". Bell 8½". Length 45¾".
