The engineering of my front door has developed over the years. I have now got a standard yale latch, standard mortice, good and tight draught excluder strips on 3 sides and now a roller catch for convenience. This means that I have no need for turning door knob but every need for simple big knobs. Where can I get what looks like a door handle but is just a simple brass knob? All I've seen are too small. Present solution is a soldered up turny knob, but it is about to disintegrate!
TIA, Mike
