My Bullet's decal says it's an 81 but I think it's actually an 83. The model number of mine is called the H-3. The pickup is actually two single coils but they're not wound together like a traditional humbucker.
The neck is really amazing on these things.
I added the 70's reflective Johnny Cash sticker to mine in tribute to Bob Wootton, the guitar player who replaced Luther Perkins after he died. In early 80's Kramer guitars made his a red guitar with a single humbucker in it he played all the time. So I named my Bullet after him!
