    Recently I bought a Getzen Super Deluxe Tone Balanced Cornet off ebay. I didn't spend too much on it and it looked like it was in good condition (the bell was not destroyed or looked to have any repair). When I got it in I oiled up the valves and noticed they were pretty dam shiny for something that should be about 50+ years old. A few days later I took them out, wiped them down and took a picture of them. And this is

    For comparison here are the valves out of my 1991 Yamaha 2320. That instrument was used for its first 6 years, and spent the rest of the time in its case. I know these valves are made of different materials and will wear differently, but I thought it was an interesting comparison.

    They don't look that old to me? Are they refinished or something? They seem to have no wear at all.

    Those Yamaha valves are probably Monel, and therefore SHOULD be dull in appearance.

    My SD trumpet valves look the same. Monel will look different too.

    The Getzen valves are famous for being tough and long lasting. When there is NO sign of wear, I get suspicious if before the sale somebody polished them down which would hurt the compression.

    Interesting. Well I'll get the compression checked, I've been meaning to take it in for a checkup anyways. The horn has a satin finish on it so it might have been reconditioned at some point. I think I got it from someone that was doing an estate auction because all they did was take a few pictures of the outside and made no mention of valves or slides, and had 1000 other types of things they were selling.

    Most of the Conns I work on have valves similar in condition, they just don't show any wear.... Pretty amazing.

    It may be just me, but it looks like buff marks at a right angle to the piston.

    I do see signs of wear, though minimal. The right angle buffing is on the stem part of the valve.
