That's a nice looking plane. Obviously it has been well preserved in its original box. Other than the finish, it's nearly identical to the Stanley #101, which was black with a black or red pressure cap, depending on its vintage. My guess is that it was probably manufactured by Sargent, Dunlap, or possibly Stanley. Your Craftsman plane, as well as the Stanley version, were inexpensive, low end models that were marketed to the home handy man. With a properly sharpened iron, and a light pass, it will chamfer the edge of a board, or plane plane down a sharp corner. It's probably not a plane I would use for fine woodworking, but still a keeper based on its condition and original box.
