Yes, Ballater if I'm not mistaken. They have a restored Victorian railway carriage there now as a tourist attraction. All the crowned heads of Europe used to get off there and then onto Balmoral by road. Queen Victoria prevented the rail line going any further, no doubt to prevent day-tripping proles from rubber-necking at Balmoral. Changed days, now they charge them to have a look around.
As for the hose, I have it on the best authority that they were definitely white, seemingly Mrs Simpson's choice.
