I need a little help with a Jackson pickup (J50?)

[thebigz]

I am putting my model 5 back together and I'm deciding what pickups to put in it. I have a few old Jackson pickups, so I figured I'd go for as close to stock as possible. One is obviously a J50N, the other I'm not so sure. The pole pieces are in the same as the neck, but looking on the internet, that doesn't seem to matter as all exposed pole pieces look to be "above" the Jackson sticker. My guess is it is a J50, but I'm not positive, hopefully it is a J50B so I have a matching pair... J50BC would be even better as I have 2 guitars with those and I love them. The only thing I can see is that the 4 brass screws have been removed from the back, or it never came with any.

Here is a picture. Black pole pieces on the front, no logo. The mystery pickup is the bottom one



Any help?

Thanks

Did you try measuring the DC resistance and compare to the resistance of the J-50N?

I'm not sure why I hadn't thought of that. Thanks.
