Let's take a closer look at several of the paper capacitors found in this radio.

Most (but not all) of these capacitors have handwritten Philco part numbers on them.
Some of the caps are Philco branded while the rest are Sprague capacitors with Philco part numbers handwritten on them.
I recall seeing some Philco paper caps with a part number such as 30-xxxx-S. I now believe that the "S" stands for Sprague. In a similar manner, I have seen Philco transformers from the 1929-1931 era with a part number such as 2766J - the "J", I believe, stood for Jefferson Transformer Co.
