Just a little foot note to the Wall unit discussion about Cado and PS
The Royal system was designed by Poul Cadovious in 1945
The CADO system was also designed by Poul Cadivious but much later in 1970.
The PS system is designed by Preben Sørensen, Randers and is completely different to the royal and cado.
Shelves are supported and fixed to the upright by brass bar which has a screw fitted through the shelf into the bottom of the brass bar.
The cabinets are supported on steel rods and sometimes with a tri-angular steel plate with 3 "pins"
I hope this clarifies.
I have some more Royal and CADO arriving shortly and will post it to the RADAR.
