My handlebars are from the seventies and I don't think the same shaped ones can be found now.
My bike used to have finned points cover and rockers caps but foolishly, when I lived in a flat and was short of space I chucked them in my scrap aluminium sack and took them to the scrap yard along with loads of other stuff. I wish I hadn't now because I can't sem to find them anywhere. I don't know who made them but they were really popular at one point. I went through a phase of thinking they were ugly but now everyone puts their bikes back to standard I want the after market bits back on!
