Question On Die Markers For 1916 DDO Buffalo Nickel

I thought I heard somewhere that the 1916 Buffalo DDO was actually Hub Doubling. Anyway, when looking at this coin online, the doubling on the feathers sometimes isn't nearly as clear as other examples and I was also told that there is a die line to the jaw from the first braid. There are several I see haha! I have an example that I thought some of you might look at for me. On the first top left feather I feel like I see some doubling northward, yet on some of the examples I've looked at, the doubling is seen south from feather. I wouldn't consider myself very familiar with the series so when I read of doubling in other areas and with all the lines used for detail on the Buffalo nickel it all just blends together...On this example, the date is obviously tricky but I thought there was some doubling seen. Now it could be Machine Doubling but hey worth a shot
