Indian Lock (from Mr Puzzle)

I have over time decided locks are not my preferred form of puzzle.  So I have this ‘sequential discovery’ puzzle to offer. Solution sheet included.

********************************************************************************

To make this auction fairer if the leading bidder has changed any time during the final day, that lot will remain open for an additional day.  This will continue until the leading bidder has retained the lead at least one full bidding day. The purpose of this rule is to give the penultimate bidder a reasonable time to counter-offer, and thus to discourage poaching. I feel this is the right thing to do as some bidders are in different time zones and may not be able to bid towards the end, unless they like sleep deprivation.  This method is used on various other puzzle auctions.
