Vintage Yard Porch Street Lamp Hexagon Glass Globe

Found in basement of my families 1940s Block style home from Midtown Sacramento . We all have a different idea where it came from on the property I said it was one of two outside lamps post that were at the end of outside stairs. My sister said it was at the bottom of the inside stair post in the hallway. My brother said the lamp globe that sat on the lamp post in our front yard.
Can any one I.d. ..age, where it may of come from and brand and anything else.
