This is a non-compensating 3 valve bell front dating to 1985. While the quality should be ok, it is more suited to marching band rather than brass band. The lack of the 4th valve will limit its suitability, and most brass bands will be populated with bell up instead of bell front horns. Getting this horn to blend well with front projection sound could be problematic. I don't know the price, but at the lower end of the market, new 4 valve compensating horns can be had from the likes of Wessex for under 2000 Euros.
