That cleared the confusion on who made the shade. Donald Newton MacDonald was the son that ended up being the head of the Stained glass lamp department of Bigelow & Kennard lamp co. So now I believe that these signed MacDonald Leaded shades are Prototypes to show Bigelow & Kennard his work and was hired and the same shades where then signed Bigelow & Kennard as we see today. This shade is very nice.
The shade is 20 in Diameter with a 3 1/2 aperture top opening. I hate to say that but I cant find a crack maybe a very small one up by the top in the green glass.The glass has a hammered type green top glass and a beautiful White Clam Broth bottom glass. The shade is signed MacDonald.
I do have the Grueby lamp base I would also sell if there is interest? This shade is very hard and rare to find. If you have a nice Bigelow Kennard base there you go. If you have questions please ask.
