Little bit of Napoleonic relic hunting going on, as I've been searching for the third of three Consul Glaives, from when Napoleon was First Consul of France in 1800. Windsor Castle has one, confirmed by the archives for me. The second is in France, shown online. The third is tricky, supposedly in the Victoria & Albert Museum in London, but no replies yet from them since last year. Must try again soon.
Shown here. For 200 years old, it's a lovely little piece of work
