Anybody recognizes this split-coil pickup?

I've got this pickup fitted in a Fernandes Revival bass I recently bought. It's not the original pickup, but I do not know which brand/type this is.

As you can see it has swirly pole pieces, and the pickup covers are not smooth but have a fine texture to them. 

Does anybody recognize it?

Kent Armstrong, or Seymour Duncan. I'm sure one of those 2 has swirly pole pieces, just can't remember which.

I think both brands have standard smooth pickup covers. These have a fine texture to them. There are no marks on the bottom. It has magnet bars at the bottom though.

Looks like it could be a cheap set. Nearly all the aftermarket pickups you can get are always magnetic pole pieces.

The ones with a bar magnet under them are cheaper to make.So it could have come from China, a squier, or someone's spares box. Unless there's any markings on them, I doubt they will be a decent aftermarket set.

Thanks for the info

The pickup doesn't sound bad. Though I'll probably put in a different one to try and see what happens to the sound.
