In my collection, I have a tenor piece by Selmer, not the usual French made, but one made in England... There's very little on the web about them. What there is suggests they weren't interesting to play (I'm pretty sure Mr Wyver would describe this as the dullest piece he's played).
I was discussing it by PC recently with another member and was asked for a few pics. The mouthpiece is nice, big, dark warm sound, not loud, but almost homely. Suits me.
It's gold plated brass, seems to have the gold straight on the brass, which means that over time the brass will migrate into the gold, affecting the colour/finish. Unlike links, which have layers of plating under the brass, and when the thin gold goes, they turn white/silver.
Something...
