Olev I bought a couple of guards of "Vintage Tin" here is SA and they are very poor quality, one I was able to use the other went in the bin.
I ended up getting the guard I wanted from Adam Higgins (03 51483207) in Vic, it was very good and I would recommend his tinware. I have spoken to Henry and am in the process of getting stuff from him, havent seen his work yet but he is very friendly. Adam mainly does mudguards and Henry chainguards and toolboxes etc.
