Any mortgage, deed of trust, security agreement or similar security instrument, or instrument supplementary thereto, or amendatory or in satisfaction thereof, covering any real or personal property situate in more than one county in this state, which was heretofore made to secure the payment of bonds, notes or obligations issued, or to be issued, by any public utility, rural electric cooperative, telephone company or railroads, and which was heretofore filed or recorded in the office of the county clerk of any county of this state, or a copy thereof was certified to by any county clerk of this state, may be refiled in the office of the secretary of state as provided in Section 62-13-8 N.M. Stat. Ann.. Refiling shall thereafter, as to any real or personal property covered thereby and not previously released, be of the same effect as if the instrument had been originally filed in the office of the secretary of state in conformity with the provisions of Section 62-13-8 N.M. Stat. Ann.. Nothing herein contained, however, shall require refiling of any instrument.
