Hi Jaygor.
I have now got the replacement knobs on ebay. They are priced at £11.99 (due to the extra machining costs & low volume).
Here's the link:

Hi jaygor.
I was asked about making these knobs by a guy yesterday, as he was also have a problem getting hold of them. He contacted me because I sell a universial knob on ebay, but he needed a bigger size to fit his Cannon SP2 gas hob.
I have now drawn them up & they will go into production...
