Until yesterday I was reading Silkstone as “Silktone”. I thought Silktone a really clever brandname (nicer than Sweetone even) but now I realise the name comes from Silkstone Common where Paul Hayward makes them!
It’s funny that Hoover whistles are renowned as being quiet. In the UK Hoover is still the commonly used name for a vacuum cleaner, which is anything but quiet (unless you’re using the new silktone vacuum I’m about to patent).
Somewhere in the long distant past Thom Larson posted a hilarious set of Hoover small-appliance whistle graphics. If you want a good chuckle, look them up.
Hey, Martin. I just did a search for “Silktone”, thinking it was the name of the whistle. Your post was the only one to put up. It saved me some time and confusion.
