Has Anyone Seen These Strat Pickups Before?

[57strat]

Hi all,
Just recently joined this forum and have a bit of a puzzler for the pickup gurus here. I have a set of Strat pickups that I "thought" came out of my 1986 AVRI 57. It was so long ago that they were replaced though that I'm no longer sure. I have never seen these before and internet searches are coming up dry. They do appear to be old but for all I know they could be foreign knock-offs. Here are the specs and pictures are attached.

The flatwork is light grey for both bottom (heard of) and top (not heard of). Pole pieces look oddly staggered compared to others from that era with slight beveling. All three pickups have purple windings with a clear protector shield around them, followed by cloth fabric tape on the outside. All the pickups measure around 6.0K ohms. Please reply if you know anything about these, thanks for your time....Dan

Haven't seen grey tops before, or tape on the wire; but the rest of it looks like 60's spec strat pickups. I'd just try them and hear what they sound like. 6k is usually bright and twangy; might be good, like surfers.

Is that an MIJ Fender? Mid 80ies Fender Japan was started and only had for a short time pickups supplied from US. Your pickups look at lot like those MIJ.

Beau is right: they are historically not correct for 1957 Strat. Those are more like 1964 onwards with grey plates and plain enamel wire.
