Are we to assume that Mr J.A.Radford and Mr. H.A.Taylor are the same individual? I only ask because the picture of Mr. Taylor on the home page looked familiar, it looked like the picture of Mr. Radford in his book on lathe improvements. On checking, it is the same picture. Can some kind person clarify the matter. Is it a case of another ME author’s pen name? All these pen names are getting confusing.
