We frequently see Lefevers with features of a higher grade gun... E barrels on an F or sear adjustment screws on a G for example, but we never see them using lower grade parts or materials to finish a gun.
Just for the record I have two G grades with Sear Adjusting screws, one a two hook gun @ SN 20,633, the other an early large hook gun @ N 29,418. My observations are this is normal for a G in this SN range, not an "Up-Grade". My FE @ # 38,025 does not have the sear adjusters. I do not know if any of the early H's had them or not, but easrly G's do. They were apparently eliminated at some point on all grades below an E, probably some where between 29K & 38k numbers.
