The Philco Radio website, has lots of information on almost all of the Philco Models ever made including Philco Factory Service Manuals for almost every single model of Philco Radio ever made.
The Model 144B Cathedral Radio sold for $65 in 1935, which is the equivalent of about $1,228.70 in todays money, which means these radios were a huge investment during the depression, almost as much as a used car back then.
