Any way to tell what pick up is which?

Is there any code on a pick up to tell me what it is? I bought some Fender Fat 50's many year ago and put in  a pickguard and trying to think ahead I put some masking tape on the pick ups I took out and wrote on the tape what they were in ink. Of course it is more than 10 years later and  the ink has faded and I don't remember which is which after all this time. Any way to tell what they are?

Fender list the spec as Neck: 6.0K. Middle: 6.3K. Bridge: 6.2K so get the multimeter out!

Thanks. Sorry if I was confusing. The unknown pick up wasn't one of the Fat 50's but was whatever was in the guitar, a guitar when I put the Fat 50's in. I assume it is a Fender American Standard generic pick up. But it could be almost anything since I can't remember where it came from.

No, you weren't confusing, I just didn't read your post properly.

Maybe a photo would give our more learned members a starting point.
