Windcraft Baritone Valve Spring Heavy

Heavier than I'd normally use, but bought to compare against light version.

Is what it says ;) that's it

Heavy tension springs bought to replace lighter tension springs for my Besson Baritone, they are great. they're quiet and responsive and not over priced.
The Swanee whistles are excellent value and work really well. After buying something more expensive elsewhere I took a chance on these but am really pleased with them.
The music stand pencil clips work fine. They only fit on the lower section of a standard music stand, but still useful and not expensive.
