Mystery Rear Hubs, Excelsior? Henderson?

[MMasa]

I have these three rear hubs that I'm not sure on. Can anyone tell me the make, model and approximate years that they would be correct for?
The one at the top in the first picture is a ball bearing hub. The other two are Timken bearing style. The Timken ones seem to be the same, except for a grease fitting in the one.
Thanks

They are all Excelsior, Mark also used on Hendersons. 1924 was the first year for Timken bearings at Excelsior.

Thanks Eric. Are there certain models that they would be correct or NOT correct for?

The ball bearing hub was used on Big Excelsiors from 1916-1923; and on Henderson from 1919-1923. Sprockets, and brake drums differed from Ex to Hen.
