I found some interesting information online, the League of Nations Armaments Year-Book. You can download it from the National Library of Scotland at https://digital.nls.uk/league-of-nations/archive/195479746
A useful information source for the inter-war period.
@rogercooper that's pretty interesting could really get pretty accurate with initial placements.
