Strawed parts
What kind of strawing process was used by DWM on the early models (1900-1906)? I have been looking at some parts from a 1906 commercial and the areas of the strawed parts that don't get exposed (i.e. inside the back of the trigger) are a very distinct brownish color. Comparing this to a WWI trigger, same location, totally different color. Was there a chemical process involved or just a heat treatment? I also noticed some difference from both of these when I look at a 1923 commercial. I see several distinct colors which leads me to surmise that there must have been different processes other than just the temperature of heat treating. Any documented strawing procedures?
