There's my problem. The replacement knot is going into brass housing on a lead crystal handle. It only sits just below the glue banding on the end of the knot. see pic at top of thread.TGN show both the plug size and the size just above that - what they call the 'tuff' although tuft sounds better. They do High Mountain in 19 and 20 mm nominal plug width so I'd say that the 19mm would be good for what you want providing you can set it deep enough as the overall height is about 65mm.
The knot which came out was 72mm and flopped about like a good un! I need to find one 50-60 mm max
