The action has a Green Mountain 54 caliber muzzleloader barrel threaded onto it.  It had an inline breech threaded into the barrel.  When I bought it the inline breech with musket nipple was installed,  making it an unusual inline muzzleloader. 
I snapped a few musket caps on the nipple and they were a pain to remove.  I can see why the action has scratches from a knife etc.  trying to remove the caps and fragments. I removed the inline breech and want to install a 50 caliber liner and chamber it to 50-90 Sharps. I  guess they cut the extractor notch rather than remove the extractor,  which helps me a lot and allows the action to be returned to centerfire.
I guess I should have said this to begin with.   

Btw, had anyone seen a RB converted to inline muzzleloader before?

I am not sure how easy it is to get a 50-90 rim to clear the hammer.  My #5 is now a 50-70 and it is all my shoulder wants and then some!  The buffalo I shot with it didn't know it was only a 50-70 and not a 50-90 and succumbed.  Tom

Yippy, when I had Higginbotham convert my 1902 to a buffalo rifle I was thinking about doing it in 50-90. He talked me out of it and said I just wanted a 50-70. Maybe the problem loading the 50-90 was part of that but he said his was a 50-70.
And I have a Westley Richards "Improved Martini" (really an internal hammer Peabody) that I had converted in the late 1960s to what now would be called an inline muzzleloader.

Ballards may be weaker,

If the lower tang is original to this action it's not an original Sporting Action. The Sporters all had a longer lower tang with a wood screw at the end of the lower tang.
I think it's a #5 smokeless action that's been milled to octagon top.

As Vall said, Higginbotham milled my #5 to an octagon when he built my rifle.

I think your correct,  after looking at other actions carefully. 
I'm happy to know it's a smokeless action.  Not that I plan to hot rod it,  but it's good to know.

That's an amazing looking rifle.  The case hardening is beautiful. How long is the barrel?
