Re: Questions about Conn Naked Lady
That's a 1949 conn 6M! Great horn! I play a 1950 6M. If it's sat in a closet unplayed for a long time, it's likely to need pads, and possibly corks, etc.
The value really depends on the condition. Prices are all over the place. The earlier horns (1934-1947) with the rolled tone holes are the most valuable. A horn like yours in good playable condition, with original lacquer, no dings and dents, etc. could bring $1200-$1500 depending on the market. It's hard to get that kind of money for them now. My advice is to look at completed auctions on eBay. That'll give you some idea what they're actually selling for.
The abundance of quality Asian horns and declining economy have really hurt the market for vintage horns like yours. Unless you really must sell it, you may want to hang onto it for a while.
