I have one. That valves on it are amazing! I absolutely adore the movement of them. It all in the corrent shape, no big dents and almost no small dents either. But obviously it is quite old. Serial number 601862 if that means anything to anyone? The lacquer is rubbed off in quite a few places. Has 1st and 3rd valve slide pushers and both move smoothly. Tuning slide doesn't but it has in the recent past so i'm sure could be budged with the right strength easily. It has a case which is in remarkably good condition. How much is it worth?
