The existing, high security, Treasury display case was fitted with a special steel divider inside the case that provided both security and a seal to allow different climate control conditions in each new display area.
The existing bottom display plates were stripped (including barrier) materials, re-sealed and re-covered.
The vertical back-boards were replaced with new sealed and fabric boards. Beacon Display provided the new and re-covered boards.
