The insides of the holes may be o.k.(if they are accurately spaced!!),but the surface of the plate,and the edges of the countersinks have been buffed to death,and the surfaces are not flat at all. I would not want my stuff to look like that. It looks like it was made in a cave by an Arab in 1903 (when they used to hand file copies of British guns out of stolen railroad rails).
That sort of thing may be taken somewhat as a joke these days, but I saw a video a while back of a guy in India making a lathe leadscrew with a file!
