Still have my old uniforms, too. I've also kept my swords (one is a regular duty model, the other has a lighter 'levee pattern' blade intended for social occasions). Obviously I no longer have any use for them, but they bring back happy memories of visiting Wilkinson's factory in Acton to have them refurbished (sadly, Wilkinson exited the sword business on September 15, 2005).
And the swordbelt serve as a good weight control device: when they start getting tight, time for a diet!
"If at any times we must deal in extremes, then we prefer the quiet, good-natured hypocrite to the implacable, turbulent zealot of any kind. In plain terms, we are not so fond of any set of notions, as to think them more important than the peace of society". John Toland, The Description of Epsom (1711)
