Need help with Bowl/Pitcher set

Can anyone tell me anything about this set. I can't seem to locate anything on it. It's clearly marked Roswell but when I start searching everything comes back about Roseville. Any info on the maker, age, value welcome.

 

Since this pattern is different, Roswell is probably the shape: https://www.worthpoint.com/worthopedia/victorian-china-wash-set-pitcher-bowl-chamber-po
I would put "Roswell" in quotes when you search and maybe look for different pieces of the set.
