I think it was more likely a return. They were available at Windsor 12-15 May. Released elsewhere UK 16 May. Apparently they're selling like hot cakes in the store too.
There doesn't seem to be a Ltd Ed number mentioned anywhere but there's only 12 more days to go to the official celebrations so I don't think they're going to be churning any more out in Lyon.
People who still want one, I suggest refreshing page now and again to check for returns or 'anomalies' before restoring to flipping flippers: https://www.hermes.com/uk/en/product/voitures-exquises-scarf-90-limited-edition-H0005117v16/
I recalled seeing a figure of 500 somewhere and have scrolled back here to p.62 where @Meta shows the scarf and mentions 500. Sorry for not doing a proper inserted quote but am still familiarising myself with the post/reply/quote actions!
