This is the beauty queen of today’s photo shooting! A very nice Conn 70H! The two tone silver finish is gorgeous and in very nice shape except some spots where the lacquer has come off. When it came to me it was nearly entirely black, after a very light polish it looks really nice again.
I initially posted this trombone as being from 1966 wich is of course impossible since Conn discontinued the 70H after 1955. The serial number on the slide handgrip of the slide indicates H41xxx. Also the metal on that section looks slighty different. So that makes me think, the slide grip may have been replaced sometime. The outer slide looks original to me as do the slide inners.
This remains us with the question, when this trombone was made. The engraving on it may indicate it is from before 1945. A previous owner also contacted me with some precious info on it. It looks like this trombone was originally owned by the bass trombonist of the Oslo Philharmonic in the 1950’s, Lyder Vengboe. It may very well be the bass trombone played on this recording of the Grieg Piano Concerto from 1961: https://youtu.be/9tc0ljAFMCU
And those two pictures seem to indicate that he already played that Conn in 1952 on a tour in Norway:
So it is at least from before 1952. Nice shape for being that old!
Slide and valve are fast and silent although there is some wear on one of the slide inners. This is the “long slide, short bell” version and it produces a glorious sound!
