I looked at an Ithaca NID trap gun with a single trigger that does not appear to be factory. The trigger itself appears to be cut out of flat stock with the sides flat, sharp edges rounded, nicely shaped and bright(not blued or plated). The selector is on top of the tang with one position being L(eft), the middle S(afe) and the other position r(ight). Could this be a Miller trigger? If so, would it add or detract from the gun's value in relation to a factory single trigger? If not, any ideas? I didn't see any markings on the trigger itself.
