The reason I left Henry's out of my discussion is simply numbers. While among the oldest of lever gun designs, Henry's were out of production for so many years, only fairly recently being made again, that the numbers in the hands of shooters is still quite low.
There are many designs of lever guns currently in use in very limited numbers, compared to the Win 94/Marlin 336 and pistol caliber guns. Some are long out of production, others only produced in small numbers recently, and not what jumps to the mind's eye when someone says lever gun. Guns like the Winchester 88, Sako Finnwolf and Finnbear, the Winchester 95, 86, and 73 for instance. And even though the Savage 99 is our of print, its long production history has kept it in place in the forefront of classic lever guns, many, many of them are still in use.
I also have to wonder, why the huge numbers of .22 lever guns have been left out of the discussion. True, the semis dominate and have for decades, but I think .22 leverguns hold second place still today. Bolts and single shots are strong as initial trainers and target guns, but in the field, taking everything from rats to raccoons, odds are, if its not a semi, its a lever.
