I am so happy that budget was mentioned. It is probably the number one reason that old trumpets are so valued.
In my case, I have some notable exceptions:
1) the playing qualities of the vented baroque trumpet have improved immensely in the past 15 years
2) the playing qualities of Monette trumpets have improved as Dave Monette has learned things
3) the consistency of Bach trumpets has improved immensely since Ted Waggonner took over QC
4) the Xeno series of Yamaha trumpets represents a major advance in the art of perfecting trumpets
5) Schilke horns have maintained consistent quality over the entire life of the company (excepting certain partnerships.......)
6) Getzen horns have maintained a consistent quality regardless of age!
I know that this is semantics BUT to me vintage is horns from the 50s and earlier, not the 60s and later. Manufacturing took a turn when Bach left Mount Vernon, and if we research carefully, we see names like Fullerton and other first attempts at economic consolidation happening about the same time........
