If the English lady was Alison Balsom, you shouldn't have much trouble locating her.

@administrator said in Trumpets Made ONLY by Their Maker:

Besides Monette, Harrelson, Getzen and Conn-Selmer (and the now defunct Kanstul), I do not know of any American trumpet makers that truly make 100% of components in-house (excluding spit valves, of course).

Kanstul isn't defunct - yet. They're still breathing, but the life support plug may be pulled at any moment.
