I attached some pictures. It has some weight to it. It's a little heavy, but small. Measures approx. 3" wide and between 2" to 2 1/2" tall. Takes 1 AA battery to operate. It beeps for an alarm. I can't seem to find one like this on eBay nor Google images. I tried asking on an antique radio forum, but no luck so far. I'm looking for the worth and etc.
