So, does anyone know how I can do this, please? No local joiners are willing to take out one and copy it, as far as I can tell.
Wickes, Travis Perkins and B&Q/Homebase don't have any the same.
Do I just get used to living with three missing staircase spindles, or is there some magic cure I haven't thought of? I'm in SE London, if anyone knows someone here who can help!
