Shadow meters were not a feature exclusive to Philco, but they probably used more of them in more models, and used them for a longer length of time,
then anyone else, 1932-1938 if I remember correctly. They never did go with the magic eye tube idea, which was just as well, probably in part because RCA held some of the patents, the last thing that Philco would do is pay royalties to RCA if they did not have to.
