Pre '30 Implement & Farm Primitives Auction

This auction uses Extend-All Bidding!  If there are ANY bids on ANY item within 5 minutes of the auction closing, ALL items will extend for ANOTHER 5 minutes until ALL bidding has stopped.  This means that all items will continue to stay open even if there hasn't been a bid within the last 5 minutes.  This gives bidders that have been outbid an opportunity to bid on other items before they close.   **If auction is extended past 30 minutes, then extension times will decrease to 3 minutes. If auction is extended past 1 hour, then extension times will decrease to 2 minutes.
