Wire of this kind was sold by General Electric below the trade name "Deltabeston." The value could possibly relate only to the fact that a piece is an authentic relic of bygone days, or an object that can serve as a conversation piece or item of dwelling decor.

The underside surfaces in the skirt area are often heavily stained with a coating of stubborn train smoke.
