This is a 1964 Silvertone made by Danelectro. The serial number is 5104 which shows it was made the 51st week of 1964. This is the higher-end two pick up amp-in-case model. This guitar has two lipstick pickups. This model is part of the amp-in-case line but does NOT included the amp-in-case.
This guitar is in excellent condition for it's age. It is 100% original. There are a few nicks and the finish is cracking in places but that only adds to it's character. The back of the neck is worn from playing. All the electronics work properly and the neck is straight. The action is set medium. So you can use this for slide or have it set up to your taste.
Here's the original description from the 1964 Sears catalog:
