I believe it has to do with the differences between rust bluing and hot salt bluing...Hot salt bluing involves immersing the item in a liquid solution of bluing salts...(IIRC)...
But I don't think I've read a description of how the rust blue was applied...Brush maybe???
Someone who knows must inform us...
