GPO No.4 Backboard Furniture for 121 telephones
We have managed to secure a very limited number of hardware packs which includes all the metalwork required to make up a replacement No.4 wallboard for a 121 telephone. Included with the pack is a drawing for the wooden parts.
Complete original boards are very hard to find and attract a premium price. With this pack a reasonably able woodworker can easily make up a board to make a 121 telephone complete.
