I believe only the higher grades included the extra adjustments, such as seen above and the forend lug adjustments.

Jim,
I was under the impression that all the early sidepivot lever guns were fully adjustable. Wasnt the F grade the lowest grade of those early guns? I need to dig out my book and refresh.

My DM Lefever boxlock is pretty adjustable too, so I think it is early and late guns with the most adjustments.

There are so many varibles & "Overlapping Features" found on Lefevers it is hard to make concrete statements. "However" the following will I believe be found "Generally True";
The F grade was introduced close to the time of the Rod Cockers (AKA Automatic Hammerless) which used a vetical bolt entering the rib from the rear. To the best of my knowledge all of these had the adjustment screw in top tang, as well as forend lug adjuster, split bbl lug with adjusting screw, sear engagement screws etc. These were made in both thumb push & side pivot levers. About 1890 the "Two Hook" cockers were introduced & the G grade was added about this time. The bolting was changed to the "Self Adjusting" wedge as an extension of the top lever entering the rib from the left side (looking forward), thus the bolt adjuster was eliminated (Not Needed). Somewhere along this time the split bbl lug was also done away with, but the sear engagement adjuster & forend lug adjuster were retained. I have a G grade SN 20,xxx (Too lazy to go look for complete #) which has both. A Large Hook G #28,xxx & F #38,025 (I remember it, is my first Lefever) have the sear engagement screws but the forend lug adjustment had been done away with. At some point the sear engagement screws were done away with on grades below E. To the best of my knowledge this was the only adjustment which was grade specific, & that only in later years. But then to quote Russ, "I Could be Wrong". Essentially later grades F & lower had the ball joint & wedge bolt, with E & above adding the sear engagment screw. For the most part, the others weren't really needed anyway. As to the sear adjustment, I have always "suspected" it was figured most guns lower than E would be used primarily as field guns with the sear engagement being reserved for those which would see more "Target" (clays or pigeons) use.

Looking through my "Uncle Dan" book, I find discussions of the adjustable features but no clarity as to whether they were grade specific or specific to a particular time of their manufacture. I'm quite happy to accept Uncle Two-piper's" explanation. I just finished making a set of sear pivot screws for the 1900 G Grade I bought from Jim A. My 1905 G Grade has a through pin, instead. I really like the screws for easy disassembly.
Thanks,

Why Thank you TT! I am afraid tho that the great State of Kansas can only claim one of the discerning gentleman. The others were Joe Wood, from Texas, Mark Gruber, from New Mexico, and Peter Burk, from Georgia. I think my "E" 10 bore (aka Coyote Killer) has the adjustment shown. I'll look in a bit, as it is still in the truck...

Last Dollar please tell Joe I think his problem is that he is closing the wrong eye - to leave the one over the barrels open and close the other one.

Best,

Mike
