Felt Pen Marks on Pickup (Bar) Magnets

Hi Everyone, I have a quick question about marks on some pickup magnets.

I'm a mod my guitars a LOT and, while swapping out some '68 P-90's for Fralins I noticed that the magnets in the old pickups each had 2 black sharpie marks on the edge. Two days later, I'm putting a T-Top in different guitar and noticed that that magnet in that pickup had 3 pen marks on the edge.

My question is, are the marks indicating magnet type? i.e. 2 marks for A2 and 3 for A3?

Thanks for any clarity you can provide.

Larry

Confirmed sighting. I was looking at a P-100 and a T-Top and they both had bar magnets with 3 pen marks on it. I strongly suspect this is an alnico 3. I put one in a Burstbucker pro and it smooth out that nasty ass puppy quite well.

Case closed.

No, pen marks on vintage pickup magnets were used to indicate the orientation so they didn’t screw things up. Used to indicate the north pole on a magnet. North goes toward the screw pole side on a humbucker.

That kinda makes sense if not for the fact that the pen marks are on the long side of the pickup on the short side (poles). Sorry for the lack of clarity on my original post.

This is an alnico 3 magnet from a 80's T-Top.

Yes, the long side with marks is north. The short sides are not the poles.

Thanks Wilko, I'm a little confused AND I don't have a compass. But confusion is the gateway to learning so thanks man.

that's not a gibson humbucker magnet.

Yeah, Gibson used a special magnet with poles oriented along the long sides.
