I have another English cello, made around 1800 or very early in the 19th Century, (so, I suppose, Kennedy school) of a completely standard size and in good condition. For some unknown reason it sounds wonderful. This one's £17,000.
Yet another English cello, circa 1835, by Thomas Kennedy is now available at £30,000. Why so cheap? It has a tiny repaired soundpost crack in the back. But that doesn't affect the sound.
I have a nineteenth century German cello from Mittenwald at £6,000.
I have several other instruments of varying qualities between £1,350 and £3,000, and two three-quarter size cellos.
