The case in the Museum entrance hall contains The Henry Challenge Vase (its first public outing for … maybe a century?), a silver salver made to commemorate the Royal Review of 1860 by the builders of the staging used at the Royal Review in Queen’s Park in 1860, and a QERV busby … not necessarily THE busby as worn in the iconic Henry portrait photo.
(Sorry to say two light bulbs are currently out in the case).
