Avondale now sell reproduction ones if you arent fussed about originality.
Hi Chilly. They are indeedy! After the dark grey versions.I think I must have some John. I reused a 42 box years ago and that came with the knobs. Are those the ones you are after...?
Ta for posting that Looks far lighter coloured than either of the current so-so condition knobs on my 42.5, and had no idea those are the going prices now - yikes!
I'm just back from holiday, I'll have a dig around and find the ones I have.
