When were ceiling rose junction boxes invented? They appear to be post WW2 as I have been unable to find any that are older. The ceiling roses I have from the 1920s and 30s are either purely mechanical or have terminals just for live and neutral for the light fitting. Were ceiling rose junction boxes intended as a cost saving feature when constructing houses?
Does anybody know where to find old catalogues of wiring accessories as this will help to identify approximately when ceiling rose junction boxes first became commercially available?
