@ Mark: not having owned a 60s Bird, I'll take your word on the Lulls. But they're extraordinarily expensive in the US, and I imagine that they would be even more expensive in Finland, where Pekka is. He's got someone willing to make something similar to the originals, and (I assume) at a price he can afford. I encourage that.
@ Ken: they're not like mudbuckers. Bill Lawrence is the one who told me that they were constructed like the original Melody Maker pickups. i.e. with the coil wound around a blade magnet rather than steel polepieces. Except that the Melody Maker was a single coil, while these were humbuckers.
Somebody here has the approximate DC resistance specs. I recall the wire being AWG #42 like most Gibsons, but I'm not sure.
