68.—Where any goods of a bankrupt are held by any person by way of pledge, pawn or other security, the Official Assignee may give notice in writing to the holder of his intention to inspect the goods and, where such notice has been given, the holder shall not be entitled to realise his security until he has given the Official Assignee a reasonable opportunity of inspecting the goods and of exercising his right of redemption if he thinks fit to do so.
