This Constellation is not a restored horn, so the starting bid is $399. Certainly it will go higher, but the ending price may be friendlier than the Conns that have been restored. I don't see all the trigger pieces, but it's hard to tell. Seller has 100% positive rating. He says it is from about 1960. He also says it is fitted with a large receiver, but I question that. In fact I would suggest asking about that. They came originally with a medium shank and it was not uncommon to find one retro-fitted with a small shank receiver. The deal includes what I think is the original case.
