Hi, would anyone happen to know why this coil has 4 leads?  I was expecting only 2.  Pic only shows 3 since one is broken.  It's from a 1930's era horseshoe magnetic pick-up.  Asking here since I've been following the rebuilding guide which has been very helpful.  
Also, does anyone make new coils like this? Thank you!
