Thanks for the heads up Wayne. Eventually, I'm sure that I'll buy things from many different vendors, so I guess I'll just make the call as I go. Looking at Bix burners, and I think the UK is the only place to get them. (?)
Classixs, thanks for recommending Peter Schaeffer in Germany. He has responded to me already and has everything in nickel plate as I wanted. His shipping charge is much more reasonable than another vendor that I quoted. I'm not in a big rush, so if it takes a little longer to get the parts, it's OK.
