Philco made the changeover during the 1937 model year. Some 1937 models have been found with cloth-covered AC cord, but most seem to have had rubber. As was Philco's wont, they used up their old stock of cloth-covered AC cord before making the switch to rubber. All 1936 models appear to have had cloth, and all 1938 models had rubber.
