I think you were correct right from the beginning...it's probably not a rising bite at all...the rib extension dolls head looks like the rib extension on the 1910 gun minus the two bites...
That sideways dig about "banjo work" has been stuck under my craw for a few days now...it sounds like some unnecessary insult referencing Deliverance (the movie)...Emil Flues was arguably one of the greatest gunsmiths America ever produced...he put Ithaca on the map...
I forgot to mention that Flues worked closely together with Harry Pope...he also worked on the Thomas Flyer...oh yeah...Flues was the final fitter assembler of every Newton Rifle Corp's rifles including the one ans only Newton leverbolt (not Meachem Newtons)...in fact, Rudolph Kornbrath's personal shotgun was handmade by Flues...it now resides in the Winchester museum...Flues designed the most commercially successful SXS manufactured in America...if those accomplishments are banjo work, then I'm anxious to see that posters venerated work from on high...he is so lofty that he can look down on Emil Flues as some bush league gunsmith...if you show yours, I'll show mine
