Found in the files at Steam Tech on Yahoo.
Identified as a page from the last UK Boiler Code that referenced steam locomotives circa 1969.
Note inner 14mm and outer 16mm firebox thicknesses, also 16mm door sheet (firebox end plate).
Compare with Master Boiler Makers Thread.

Metric translations:

10mm = 3/8" approx. (+ .019")

14mm = scant 9/16" (-.012")

16mm = 5/8" (+.005")

32mm = 1-1/4" (+.010")
