Lithgow Small Arms Factory 1912 (drawing 2012).

This is my 2nd factory image of the workers at the Lithgow Small Arms Factory. The machines are lathes; I'm assuming gun barrel work. As far as I was told, the image/photo I used was taken in 1912. Rather difficult to sketch this one, but happy with the result.
