Waddesdon is a notably strange place, an 1880s fake French chateau
filled with top-end antiques and interiors salvaged from real
chateaux. It was built primarily as a museum and weekend retreat,
little changed since 1898, bequeathed to the National Trust in 1957
and managed for them by the Rothschild Foundation -- nobody lives
there. TV documentaries have shown how Lord Rothschild keeps a close
eye on it and buys bits for it.

It's interesting that the Rothschilds never got into music -- there
is a single, if fancy, piano at Waddesdon. Basically the collection
predates the mechanical music era. There's a small mechanical organ
in the collection but that was added in the 1960s, an item accepted
by the government in lieu of tax.
