(b) If the Commissioner finds the accounts to be inadequate or incorrectly kept or posted, he may employ experts to rewrite, post, or balance such records at the expense of the person being examined, if such person has failed to correct such accounting within 60 days after the Commissioner has given him notice to do so.
