About a month ago I lucked into a VERY ancient and collectable York Weldon Model cornet with the original case,( in great condition ), and all of the toys that belong with it, even the lock key. This blows my mind, considering that the little horn was made in 1901.

When I got it the valves were a bit leaky, taking away a good bit of the enjoyment of playing it. I cleaned the valves thoroughly with denatured alcohol and when they were completely dry I applied Break Free CLP as a valve lubricant. After replenishing the CLP three time I can find no leakage or loss of compression and the valve action is lightning fast. The little horn now sings!!!

Heck yes, I am bragging. I feel very lucky to have such a jewel in my 'accumilation'. It even came with a low pitch leadpipe 'bit' to put it into A 440 pitch.

My intent for the long term is to hone out the cylinders, spin the pistons in my machine lathe to true round and copper plate them back up to a very tight fit, prior to lapping them for smooth action.
