You won't find that one in that book, but it is in the Gallery - although the picture is very poor (only thing I could find, and no one has offered a better one).

It's a mid-1937 addition to the Philco line, and came in the following flavors: 37-34F, 37-38F, 37-60F, 37-61F, 37-62F, 37-89F.

Of those models, the one in your local museum definitely is not a 37-34F or 37-62F since these have three controls, not four as shown. And I can't really tell from the photo but it seems that the tuning is a dual control (knob within a knob), so that narrows it down to the 37-61F or 37-89F.
