I have always thought that Cecil Sandford was under-rated. He didn't seem to get as much acclaim as the other British former World Champions of that era. He was a before my time, I started watching in the mid 70's, but Duke, Surtees, Les Graham, Bill Lomas and even Bob McIntyre were still pretty famous even in the 70s. He and Fergus Anderson seemed to fly under the radar, yet both were multiple world champions.
Was Cecil a quiet character and less inclined towards the limelight, was it because his titles were in the smaller classes or was it something else?
Looking at the photos above, he doesn't look like he was particularly small in stature and although he rode in all the solo classes he seems to have had most success in the 125cc category.
