Section 378-D. Preservation of books and records

Every savings and loan
  association shall preserve all its records  of  final  entry,  including
  cards used under the card system and deposit tickets, for a period of at
  least six years from the date of making the same or from the date of the
  last entry thereon; provided, however, that preservation of photographic
  reproductions  thereof  or records in photographic form shall constitute
  compliance with the requirements of this  section.  Notwithstanding  the
  foregoing,  the banking board may prescribe by regulation such period of
  time longer or shorter than six years during which all records  kept  by
  savings  and  loan  associations  as  fiduciary  shall  be  preserved in
  original form.
