I know what you're saying, and I would have thought the same thing, but I got four of them, all exactly alike, and I bought them with a bunch of odd new old stock Gibson Parts, from guitars I didn't even know they made, and if you seen these, you could tell that they were never put on a guitar, and there is no tell tale signs that there was ever any screws in the back or the covers being off. the only other pickups I seen with about the same wires from this time is from the Gibson rd artist with the moog electronics and they only measured around 3.50k and the wires had a clip on the end that hooked to a pre amp
