You are close Taterz. You need to search in LSB-MSB order. The four digit hex number you have must be split in to two pairs of hex numbers and then reversed. As in Duncan reports 73110kg of spice. 7311 to hex is 1C8F. Search for 8F1C. In the unlikely event of more than one 8F1C strings, it will be the one near the end of the save game file. If the sun and moon move between Duncan's report and you saving the game, than spice stocks will be higher than the value you are searching for. The time updates every one minute of real time. And you could ask for the report near the end of a minute. If it doesn't seem to be working just load the saved game, ask Duncan again and the immediately resave the game.
