IMHO, vinyl-covered wire is the best candidate for the mystery object. It is difficult for any rope-like cord to maintain the straightness of the prong-like extensions shown in the photo unless there is something that reinforces the rigidity. Wire under the white vinyl coating would provide that. The Ramseys bought the house on 15th Street in November 1991 and Patsy had the ugly stucco addition put on the original Tudor brick in 1992. There was lots of re-wiring done for the remodel, and it's conceivable the mystery object was some kind of wire left over from that project.
