The 6H has #3 bore (0.500"), and was built from 1919 (but possibly earlier) to sometime between 1926 and 1930 (top picture) and reinstated from 1937 to probably 1979 (bottom picture). Previously the 6H had been said to have been reinstated in 1947. I now have a Conn brochure dated September 1938 that does list the 6H. However, the 1930~1931 catalog doesn't list the 6H. I suspect the 1947 was an error in the original model number list.

The "Artist" name in trombones (and saxophones) is equivalent to "Victor" in trumpets and cornets. Even the model number 6H and 10H are the same as the 6A/B and 10A/B. It is my understanding that Frank Rosolino used to play the 6H. If you are a trombone player and don't know who that is, might I suggest you look for him under "jazz". He played with Stan Kenton in the 1950's but also recorded under his own name in the 50's, 60's and 70's.
