Good stuff, although as is the trend with these Anglo-American sources, a number of smaller countries seem to have been forgotten. For instance the steel and iron commodity production of Finland in 1939 included:
-29,055 tonnes of pig iron
-5,761 tonnes of iron mixtures
-73,131 tonnes of castings (all metals)
-98,089 tonnes of rolled steel and iron
-16,376 tonnes of nails
-11,759 tonnes of iron wire
-1,972 tonnes of bolts, staple nails and rivets
Etc.
There is no mention of any of this in the study, which seems to be an error. I wondered if this was instead because of some threshold of production that a country had to meet in order to be included, but this can't be the case as for example Bulgaria with her very small production is included.
Source on the production figures:
Statistical Yearbook of Finland, 1941, p. 118 (only in Finnish, Swedish and French).
EDIT: Regarding the above figures, they only include commodities produced in the territories left to the country post-Treaty of Moscow (13.3.1940). In other words, the real numbers for 1939 were likely higher than the above.
