I shall take some, as best I can without dismantling, today.
Hi Adrian - I hope you have not gone to too much trouble as I managed to get into one today, the same year as my joker.
Dimensions are as follows:
Width (left to right) = 116cm to metal edge
Depth (front to back) = 54.5cm to metal edge
Thickness of board = 1.9cm to metal edge. The board is slightly thinner, 1.9cm is top to bottom including metal.
Brackets - 4cm x 4cm plates, positioned to the outer edge of board
The brackets do not need to hold any weight, they are purely there to allow the bed board to travel in the grooves. The weight of the board/person is taken by the shelf when the board is in position. The original board could do with being thicker or have strengthening bars in it.
Looks easy enough to make.
