Here is receipt from the Holdsworth I purchased from Robert Badger of Robert's Rebuilds in London, England in summer of 1973. I had corresponded with him by mail from home in Nova Scotia asking for a frame to be built up in the touring kit I requested. Never knew what model frame it was until repainting it a couple of years ago when I found an oil soaked piece of paper protruding into bottom bracket from seat tube. It was a 1965 Typhoon.
