I popped over and read Haddock's article. His traditional home brewed finish is actually the recipe taken from James V Howe's, "Modern Gunsmith" published in 1938. Howe also has three more variants of this BLO based finish that add increasing amount of Japan dryer. I have used this many times but only as a 'refresher' coat over an existing clean 100 year old oil finish that is most likely BLO based.
