I think you may have trouble finding a Norica trigger, I'm not sure they sell anything more than basic parts, spring, seal, etc. Following is FYI and may help you if you don't know already..Beeman has an "RS2" trigger on some of their Chinese manufactured rifles. Those guns are basically Norica copies with a cloned trigger like you seek. The Norica trigger and Beeman clone trigger are swappable. You may have to acquire a whole rifle, either Beeman or Norica to get the trigger. Maybe post a "wtb" in the classified for just the trigger or for a parts gun with trigger. Maybe contact Beeman, they may well sell you a trigger assembly.Do be careful when doing so as Chicom Beemans has used several different variations of the trigger, all inferior to the one you want which is a true two stage trigger with a total of three adjustment screws. First stage, second stage, and pull weight. As stated, be careful, Beeman actually has a rifle called an RS2 and it may or may not sport the nice two stage trigger. When in doubt, get pictures before purchasing. While the RS2 trigger isn't machined quite as nice as the Norica, it is a close second and is perfectly usable with a little tlc. Don't forget the trigger you seek must have three adjustment screws, all of them on the backside of the trigger blade, two in the blade, and the pull weight screw in the trigger housing behind the first two adjustment screws.
