Hi Des, presently I am 'safekeeping' a set of unmarked Bundts made by a German Company by the name of MELBER. They belong to a friend of mine who has fitted 15" Bundts to his Milan Brown 6.9.
Obviously, they are 14", but where they differ to the normal Mercedes Bundts is in the width of the outside lip of the rim. They are very similar in that regard to the 15" Bundts. I also believe that they are forged rather than cast alloy but I stand to be corrected on that statement. They are considerably heavier and more solid than the standard items. Regards, Styria
