While the cited Oildom article names the refinery purchaser as Waite Phillips’ recently-organized “Phillips-Highway Refining Company,” the “Highway” part appears to be a typo or misunderstanding. All other sources point to the refinery owner as the “Phillips Higrade Refining Company,” a subsidiary of Waite Phillips Co., organized in July 1920 (see subsequent footnote).
