Welcome to All Music Inc. (20k feedbacks on our other account Musicdungeon), you are looking at a great piece. 
This is the Seymour Duncan Saturday Night Special Nickel Bridge Pickup.
Wiring: 4-conductor shielded. Magnet: Alnico 4. DC Resistance: 9.75k Ohm.
Unlike traditional humbuckers, the Saturday Night Special humbuckers are voiced to be a little hotter and fatter in the bridge position, and a little clearer and less “wooly” in the neck. 
They’re more aggressive than 50s-style models, but without the compression of most high gain pickups. 
The cleans are warm and musical while the overdriven tones cut through without being harsh in the highs or cloudy in the lows. 
These bridge the output level gap between vintage 50s and modern humbuckers, making this pickup set perfect for replicating those legendary late-70s arena rock tones.
The Saturday Night Special Set is made in Santa Barbara, California. 
They come standard with four-conductor wiring, maple spacer, and short mounting legs.
