pair of old antique early GE architectural fuse holders with Edison sockets & 1901 patent

Two antique 1920s vintage, architectural or industrial ceramic fuse blocks. These porcelain fuse holders have two standard Edison sockets in each to hold fuses (or you could wire them to display antique light bulbs), one fuse for each electrical wire. They are made by General Electric and have several patent dates on the back. The latest patent date is "Jan 8, 1901". These measure about 3 1/2 inches square.

They are in excellent vintage condition with no chips or cracks to the porcelain.
