That photo is a trip down memory Lane as I was a typesetter from 1955-1967.
The machine in the foreground looks something like the old Linotype #18, with a 28-channel side magazine for special fonts. A tad later design though.
The machine was a marvel of engineering and I loved working on it. I half suspect I’d go back to it if they ever came back.
The max speed was seven lines of straight matter (news) a minute. I had some friends who worked on porno books and said they pushed the machine to the max because they wanted to get to the end of the story before a shift change.
