The Official Receiver or liquidator may within 28 days after a proof or in a
            voluntary liquidation a statement estimating the value of a security as aforesaid has
            been used in voting at a meeting require the creditor to give up the security for the
            benefit of the creditors generally on payment of the value so estimated with an addition
            thereto of 20 per
cent:
Provided that where a creditor has valued
            his security he may at any time before being required to give it up correct the
            valuation by a new proof and deduct the new value from his debt, but in that case the
            said addition of 20 per cent shall not be made if the security is required to be given
            up.
