Not sure about the bodies, but they definitely used the "lipstick tube" pickups.
From what I can gather, those old Silvertone guitars have a cult following among guitarists.
Yeah...they were Danelectros, and I remember reading that Dan Armstrong (Danelectro) designed them.. The formica body, the pickups, etc. the only real visible difference was the headstock. the Danelectros had a "traditional" 3 tuning keys on each side, whil the Silvertone headstock was set up like a Fender, with all 6 tuning keys on one side. Great deal for the money. The guitar case came with a built in Amp.
