Anyone Know What Duncan Pickups These Are?

[robberns]

I've got 2 1980's-era Duncan humbuckers in my Les Paul and I'm trying to decipher their origins.
One has a sticker that says "SEY J" on it (neck pickup) and the other says "JB D" (bridge pickup). They both have 4-conductor wiring and have black bobbins.
Any ideas?
Thanks

The SEY is a Distortion, wound by "J" (Maricella Juarez)
The JB is a JB, wound by "D". (Debbie Nyquist)

Very close...

SEY is Seymourizer which is the Duncan Distortion neck, J means it was wound by MJ.

The JB is, well, JB and the D means it was wound by Seymour Duncan!
