The missing bayonet at Trooping The Colour.
Quite intriguing. During the 2015 Trooping the Colour, one of the bayonets appeared to be missing.
See www.youtube.com/watch?v=F6VIWTVxtMU and watch closely at 29:42.
From the left – is there a seventh bayonet?
So if you happen to be seeking a buyer for the bayonet which you found near Horse Guards Parade, may we respectfully suggest that you first offer it to HQ Household Division, Horse Guards, Whitehall, London, SW1A 2AX?
