As the owner and user of a baby brother made in Asia I found the first shot the most interesting. I am guessing you found it in Tasmania where my other guess if was used to service wheels/axles of locos and rolling stock. I did once see a machine at the Hillside Works [ NZ Railway Dunedin Workshop] turning chunks the size of my little finger off a wheel ... very impressive. That machine was enclosed for safety reasons.
The other shots I assess as photographs where to me they are all too wide to be of interest.
As I guess you are using an Adobe product I suggest adjusting the black and white points, a little lightening of the 'red wheel' area and a touch of sharpening ?
The lathe is interesting in that the drive is at the opposite end of the machine to what I have ever seen or read about
edit... there seems to be a bit missing with I wonder what drove/adjusted the cross-slide using that pully wheel? perhaps for adjustment from a safe distance when the chips were flyoing
