There are no listed artists that match the name CB Norton who could have been actively painting in 1918. There is a CW Norton who did ship paintings. I can help determine if you have a listed artist if you can please send images at your convenience of the front, back (do not remove from frame) and a clear in-focus close up of the signature on each. Feel free to add images at your convenience, there is not an additional charge for photos here.
Just checking in to see if you viewed your answer and if you are seeking further assistance?
Please let me know.
