The valves in question have had some hard use, and no longer have full compression, and in a couple of areas the nickel plate on the piston has worn through to the brass. Basically they've had it. I think what they need is the valve case cylinders honing true, pistons honing true, nickel plate and then honed back to fit the valve case. A full recondition in other words. I know I can get this done in the US, but I'd prefer not to have to send an otherwise decent trumpet acros the Atlantic twice. My normal answer to any repair in the UK would be First Class Brass / Eclipse, but this is about the only thing they don't seem to be able to do . So is there anywhere else in the UK that can do a good job of this for a reasonable price? Rich.
