I am a bit embarrassed to jump in here with this ugly duckling compared to the beauties here. I believe this poor ugly duckling to be a model 1905 1st, second or third change. I can't really tell and was hoping y'all could help. It's serial number places it in the middle of the serial number run for 1st change models, but that run overlaps with the second change. But then it has the large SW on the right side plate along with the patent dates on the right side of the barrel which are characteristics of the 3rd change.

So what do I have here? I know it is ugly but it was cheap.
