When you think that ALL that stuff was marked out by hand and eye, no
computers or digital scales, digital calipers whatever, it is
remarkable. The only tools they had were rulers, marking-out tools and
vernier calipers etc.

The complexity of those cylinder liners is something else, only
possibly equalled by GM and their two-stroke diesels today and
Nordberg/F-M earlier. (For those who are not aware, the Doxford engine
was an opposed-piston two-stroke design, similar to the
Fairbanks-Morse but hugely bigger)
