Or it might be a Chinese ripoff. Photo on left is a laser cut (fake?) logo. Photo on the right is the genuine Selmer engraved logo. I've looked a pictures of the Conn-Selmer Prelude and it has the name "Prelude" written on the bell. It certainly wouldn't use the name "Henri Selmer Paris".
Its yet another fake Selmer from China, apart from the engraving the "s" on the neck octave is quite different on these, the mis-shaped low C key is always a give away as well, we even saw one once engraved SEMLER on the bell.
the two companies have in common only the origin of the Selmer part of Conn-Selmer founded by a relative of HENRI SELMER PARIS FRANCE but they are different and separate companies. CONN-SELMER is the American distributor of HENRI SELMER
This horn is a Chinese fake where the Henri Selmer logo has been laser etched on the bell.
I have seen several of these around. The seller and advertisers of these horns should be prosecuted under the laws against the selling and spreading of the counterfeits in the UK which should have been made or will be soon made in a criminal offence.
I didn`t realise that Conn-Selmer USA and Selmer Paris were different companies, I thought the former was the cheap arm of the latter, rather like Squier is to Fender or Epiphone to Gibson . Thanks Milandro ..
