The eb slide for a Holton 177 could be manufactured by a competent repairman. It is unnecessary anyway. If you can't transpose the most basic of keys then you can't play opera at all. An E crook might be a better idea if you needed such a crutch-don't forget that you'd have to change the B slide as well.
In regards the single, you'd be better off finding a vintage King 4 valve or a Yamaha 322. These are both good horns that with veryfew mods become great horns. They can be had four the 300-800 range on ebay depending on condition and customization. I have a King you could have for reasonable but I won't be back home until October. The biggest recommended mod (provided the valves are tight) is an Engelbert Schmid bell ring and custom flare. The Jack Attack! _______________________________________________ post: horn@music.memphis.edu unsubscribe or set options at http://music2.memphis.edu/mailman/options/horn/archive%40jab.org
