It's a code 121.

Thanks Terry, Have you ever worked on this model?

There is a hole on right side of cabinet.. Was that factory? If so what went there?

Vecher, if you look in the gallery of the main site,  https://philcoradio.com/gallery2/1933b/#Model_16B   , you see that the description of this model says it has a squelch control which was turned on and off by a switch on the side panel, and controlled by a potentiometer on the back of the set.

Yes, Philco calls it the QAVC switch #54 on the diagram. I think your tuning shaft is missing a threaded hole in it's center.

Some 16B sets used a tuning knob with a set screw on the side. These will not have the drilled and tapped tuning shaft.

Have No clue to what you guys mean ...

I don't know that I've seen a rosette knob w/ a set screw in the side. I have in the front and hex w/a screw in the side.

Skip,
On the early 16B'B the two speed tuning mechanism requires that you pull the tuning knob out or push it in to change speeds. Most of the knobs have a spring steel clip that holds them onto the shaft. On this sets it needs screw to hold the knob in place. When you use a non set screw knob it will pull off. If you look closely at the 2nd gallery pic you'll see a hole in the tuning knob. That one is missing the screw. The later model sets w/ hex knobs had a small set screw in the knob.

YMMV
