Madison does give figures for national GDP, but corrected to 1990 dollars.
In 1939
France - $200,840,000,000
Austria - $27,250,000,000
Germany - $374,577,000,000
UK - $300,539,000,000
Comparing German absolute and per capita GDP suggests the figures for Germany do not include territorial acquisitions.
Again, these figures are adjusted for inflation to 1990 dollars.
