Help identifing pickups?

[FritzM]

I won these Barts off evil bay and the seller doesn't know the model. Any guesses? 94J, maybe 9J#1. Damn, I hope they are for a 4 string.

Any help would be appreciated___Fritz

the model number should be scratched on the copper plating on the back of the pickups - the auction pic is too small to see if it's there or not
