1980/81 westone thunder 2 guitar needs 3 control knobs

I have a guitar as described above that needs 3 control knobs. Originals were the brass knurled style, but i guess you all know that.
The guitar is in original condition apart from the knobs ( and the strings of course)
I am two minds whether to keep it to be honest, its just sentimmental really, my mum bought it for me when i was 18
Any idea where i could get some of the knobs? I know they can be machined, but i. Can only find a us guy who does them
If anyone can help i would really appreciate it.
Cheers Mike

Mike have a look at my reply to your post in the Say Hello forum. There's link there.

I have 6 brass knobs which cost me £10 each, 3 I have refinished and 3 have medium tarnishing.
I'd just like £10 back for each if you're interested?
