This is from a Philco collector's site and it is a wireless radio remote from the late 1930s. It is an incredible piece of equipment.
This came to me because my elderly father, a former Philco engineer, has one up on eBay, though the photo there isn't great.My dad is one of the original hackers/makers/computer geeks/etc. Growing up I was surrounded by all sorts of wonderful things like this Philco mystery box. Its bittersweet to see him starting to sell some of the treasures.
