Hi all, I hate ask another part ID, but I am guessing Chuck will come to my aid yet again. I have what I am sure is a bottom cup from an old headset, but I maybe wrong, and sorry I don't have a pic. Its chrome plated steel and with it sitting in the normal position a c inside a diamond is facing up. The diameter that would go into the headtube measures at best 37.08mm, yes large I know and when fitted the viewable outside has no makings and tapers to the fork crown. This is a strange looking item, but I am quite sure I am correct, before I forget the ID where the steerer tube would fit is 26.68mm. Thanx in advance.......wayne davidson Invercargill NZ.......
