Benge Tune-Up Kit, UMI Trumpet

Kit looks to be of good quality, but is not applicable for my 1970s Benge ML Bflat trumpet. The valve button felts are too think (which places the valves out alignment when depressed), the springs are quite heavy in action compared to the original ones, and the black rubber washers are not the correct material, diameter or thickness for the valve stems. So in conclusion, it looks like this is a nice kit, it just doesn't work for my Benge.

Worked great although not quite as good as original parts. Valves are much faster and responsive now!

Excellent.
