Help! What is this? Montgomery Ward Radio Info Needed

[Lightfoot]

This belongs to my 80 year old neighbor who would like more information on this radio he received from his grandparents. He remembers it being in their home, but has never tried using it himself.

The inside cover has a paper with directions for connecting batteries and is marked Montgomery Ward Co. There are also a set of Newcomb headphones.
The inside components appear to be present and we'd like to know if it would be safe to try with batteries and if so, what type?

We would also appreciate any information on history, its use, model #, value or any links anyone can suggest that would lend more info on this piece.

Thank you in advance for any light that can be shed on this radio.
