Chris J (ProtoTipo) was advertising a set a little while back. Not sure if he's still got them?

If not, I'm pretty sure I have one available, if I can dig it out. I won't need them for my LB as I'll be using the type supplied by them. From memory it's in near mint condition and there might even be a second, in the same condition.

I don't live far from John so could always get it to him if you wanted him to make you a couple!

Cheers
Richard
