Proceed to kill Ancient Bombs and gather 11 Hoary Bomb Ashes. Each kill will get you at least one, and at most four. These bombs are hard to come by as they tend to hang out by themselves in the tunnels throughout the zone.
Talk to Ravorara four times - once for each key item. You will receive a total of 1,000 gil for these four items.
At this point, the quest is semi-repeatable. After turning in the key items to Ravorara, you may farm upto ten more Hoary Bomb Ash. Trade them again to Brakobrik. In exchange, he will give you more of the key items listed above, upto one of each. You may then talk to Ravorara again and you will receive a total of 1,000 gil for each these four items.
Go back to Oldton Movalpolos and trade the last Hoary Bomb Ash to Brakobrik. When he asks if you'll accept his item or not, choose NOT to accept it this time. You will instead receive the key item: Old Nametag.
Finally, go Bastok Mines and speak with Pavvke, in a house on the lower level of I-7 to finish the quest and get your reward of 1,200 gil.
