Ok time to push in the clutch pull the gear shift towards you and up (reverse gear). Lets go back a step or two. Now just because you have a low resistance across the winding you rewound doesn't necessarily mean the osc is working. To verify listen for it in another receiver as before mentioned. Also you can measure the voltage on the control grid of the mixer tube with a high resistance meter. Should read some negative voltage there. If positive the osc is not working.
Now if you like to fool around you can take your signal generator output and connect to the cathode of the mixer tube and use the generator for the local oscillator. Turn off the modulation when doing so. If you tune the generator 175 kc above the dial setting of the Philco and then tune both the radio and the generator together keeping the generator 175kc above the dial setting of the Philco you should be able to receive stations across the dial if the lo is the only issue.
Have fun
