Glass lid for saucepan (Kemptown BN2)

Hi, I'm looking for a replacement glass lid to replace a saucepan lid that a family member dropped on the floor. The damaged lid was approx. 18 cm but other sizes considered as I might be able to attach the new knob to the old one.

The old one can't be used as the thread on the knob basically broke away from the plastic so there's just a big hole where you're supposed to put the screw. I wouldn't use super glue on anything that would come into contact with food.

Thanks in advance.
