From what I read Philco went to using brown rubber power cords in 1936, so cloth was used in the 1935 and earlier models. So a cloth cord, a brown one, would have been correct for the 1934 edition of a model 84, as for the plug I don't know, my model 60L from 1933 had a plug much like the one Rich posted, a cap style, I can't remember what my model 3118 had. In terms of vintage style plugs I like the style that is shaped like a lamp shade as it has a shank you can pull on, but there was a style made by the Viceroy Rubber Company that I also like, but most of those have chips out of the rubber by now.
