I completed the wiring of the oscillator stage. The two RF chokes were replaced with toroids. Once is larger, so I mounted it against the chassis using a rubber grommet. The other is small enought to hang in the air by its leads.
I powered up the unit (slowly with a Variac) with the rectifier and oscillator tubes and a crystal installed and verified that I see an RF signal at the output of the stage, so it is working. Now to move on to the final amplifier stage.
