This is a 1961 Silvertone made by Danelectro. This is the same guitar as the Danelectro U1. It has one lipstick pick up, "dolphin" headstock, a three way pick up control that varies the sound from muted to bright, and the tone & volume controls. Note this guitar has been repaired by the knobs. Also the tone pot needs to be replaced. The guitar works but the pot needs to be turned a lot to get it working.
Here's the original description from the 1961 Sears catalog:
