I am missing one beading on my window (attached photos). I would like to identify the manufacturer or get some suggestion on where possibly I can find one. The writing on the door profile says: NBC6006 33 02 N BS7413:1991
What about someone who does professional 3D printing? If you're absolutely desperate for that exact bead, it might be your only solution. I'd have thought trying to source (much) older style beads would be a bit of a nightmare.
