If a party shows that when he was served with notice under this subdivision (b)(2) he was unable through the exercise of diligence to obtain counsel to represent him at the taking of the deposition, the deposition may not be used against him.
Documents and things produced for inspection during the examination of the witness, must, upon the request of a party, be marked for identification and annexed to and returned with the deposition, and may be inspected and copied by any party, except that (A) the person producing the materials may substitute copies to be marked for identification, if he affords to all parties fair opportunity to verify the copies by comparison with the originals, and (B) if the person producing the materials requests their return, the officer must mark them, give each party an opportunity to inspect and copy them, and return them to the person producing them, and the materials may then be used in the same manner as if annexed to and returned with the deposition. Any party may move for an order that the original be annexed to and returned with the deposition to the court, pending final disposition of the case.
