It's a long shot but can anyone suggest where I can find replacements for old style pull handles for bifold mirrored doors. The handles (now broken) were side/edge mounted. All I can find are some adaptors which wrap around the door edge and which I can add handles to. I can't find any side mounting adaptors. I am not making a good job of explaining this but hopefully the photos will explain. I am looking for two complete handles or four side mounting adapters as per attached photos. I thought I might be able to find a metal worker to make the adaptors from the one original I have but not found anyone. I live in Northern Ireland.
