It does look like Magnavox, and it's in the right spot on the mask. Look at the page I've attached here, and scroll down to the Magnavox dealer brochures. The logo looks similar. The sets shown all have the controls topside, but in the last brochure page on the right, one of the sets has speaker decorations close to the ones in Steve's post.
(BTW lots of interesting pictures on that site.)
