| Description | Drawings by Varilectric Ltd for switchboards and bus-bars for the Upper and Lower Theatres. The titles of the drawings include the names of other companies, including Rank Strand Electric Ltd, Crown House Engineering Ltd and Evershed Power Optics Ltd, and it would appear that the systems represented in these drawings fit with the systems installed by these companies. The drawings are arranged by reference numbers into series - E/R, F, L, M and Q - but they do not have any clear thematic organisation. |
