This page will build over time as material is gathered. It is only for radios used in Crosleys not car radios that Crosley made for other makes.
The most common post war radio used in the Crosley is the Motorola CY8, often called the chrome nose.

The much less common 5MX080 Zenith radio looks similar to the Motorola when it is mounted in the dash, The main difference is the dial numbers and dots under them. First offered in 1947.

A third style offered mounted through the blank dash radio plate. They show up from time to time. No schematic has been found for the Philco Model # CM 5118 but two different schematics have been sent to me from two different members that think they are a close substitute. I have never owned a Philco to check them out hopefully one or the other will help in servicing your Philco.

People often ask why Powel Crosley didn't make his own car radios. Powel had already sold off his Car Radio division years before and had even sold his regular radio and appliance business by the end of WW-II. The fact is Powel did build his own radios for the PreWar Crosleys. It was part of his Romeo line of after-market car radios. They are very rare and different than the rest of the Romeo line in packaging since most of the radio was in the engine compartment. It probably only fits models with rear mounted gas tank.
