> Aren't there also rubber grommets under the screws holding chassis to the floor?

There should be, yes. Also: all of the tuning condenser grommets I have seen of this vintage Philco used steel sleeves to prevent the grommets from completely collapsing when the mounting bolts were tightened down.

Yes, Philco had a name for that but the name escapes me at the moment. The dials were designed so that the owner could note their favorite radio stations in the blank spaces above the actual dial markings.
