I was really pleased with the work by Dampertech and not to expensive either. Don't go hunting for callipers yet Chris - I have two being sent from Italy tomorrow and another being sent from Neil on the Beta Forum some time this week too.

I'd appreciate you checking my measurement against an OE part, Chris. Mine are a bit beaten up but look to be 1.5mm thick. 18 SWG may do if that's all I can get easily but If I'm going to do a copy, I want to get it right. Shiny yellow zinc passivate may be a problem with my local electroplaters - last time I did carb parts it cam back matt but so long ago that I don't remember of shiny was an option. Should be shiny, I think.
