You guys are no fun, I was looking forward to a long and tedious project and you want to leave it alone?

Well, I can see your point. I might just blue the toggle parts and the side plate, find some better grips and mag and call it a day.
As G.T. pointed out, there's no stock lug and no hold-open notch, so it would be very interesting to know more about the frame. From what I gather, the hold-open was omitted on military guns at some point, and then reintroduced in 1914. My frame seems to be very similar to the gun in this thread:

I suspect that this is a military contract DWM 19?? - 1914 frame. Am I correct in my assumptions? Also, what's your thoughts on the small triangular marks at the base of the barrel? It appears to be marred by a barrel installation tool, but the barrel matches the extension so I'm not sure.
