HELP~~73 Winchester 44 ???

[73_winchester]

I need some help~~ ~~ I recently acquired an original 73 saddle ring carbine(1881 mfg.) with a special order 19" barrel~~Was advertised as a 44-40, but will not chamber a 44-40 round~~It is .44 caliber, but which one??~~I have tried .44 Russian, .44 Colt and they wont chamber either~~I tried a .44 S&W American~It chambers, but seems a little sloppy(could be chamber wear?)~~Tried a .44 Henry Rimfire long and it seemed to fit like it should, but the rifle has a centerfire bolt~~Thinking it might be a transition gun from the .44 Henry Rimfire to .44 Centerfire switch~~Have done a chamber casting, but can't find the dimensions for the .44 Henry Centerfire round~~Would appreciate any help that anyone might be able to give me~~Thanks
