(This post is based on one I wrote for my now defunct 'St Cyr On Wheels' blog back in March 2021. I find that for one reason or another over the years I have left a trail of sad-looking, lonely, overgrown and abandoned blogs behind me, and given that I would really like to make a go of this one I have decided to move over to the new format anything from the old ones that seems relevant. Also it's easier than thinking of something new to write, but you never heard me say that.
