Looks like they're re-badged Jard triggers(or are Jards re-badged EABCO ?). I'm extremely happy with my Jard. A better mousetrap than Moyers or Kepplinger IME. I have installed and used all three.
Had my gunsmith in Maine lighten the triggers on two #1's...nice crisp letoff at 3.5 lbs. He also likes the Kepplinger....pain to install, but all he has done worked out well.
