That's an incredibly interesting story Les!

As mentioned, it's hard to say for certain which Philco model that is without more information because Philco used the identical cabinet for a number of models.

But.. we can say that based on the list of possible models it had 6 tubes (different tubes depending on the exact model).

Would the woman pictured know if the radio ran off of batteries or was plugged into the wall?

AC and AC/DC sets include 38-9K, 38-23K, 38-40K, 38-89K.
The rest are battery operated sets.
