Those are very old...more recent pickups have ID info. I can't help, but can tell you these look just like my old Dual Sound pickups, which I believe were the first pickups set up for coil splitting. I bought some of these when they were newly introduced in the mid- to late-70s. So I'm guessing you're in that era. Some suggest using a meter to read the coils. That alone might get you an ID. The PAF and Super Distortion were other variations and I'm fairly sure did not bear any labeling.
Not much help but hopefully a voice in the distance is better than silence.
Regardless, these are great pickups and I would find a home for them and play them loud!
