Well, I'm quite willing to entertain this claim, but your response doesn't provide any details about who sold tungsten to Germany during this period. I don't want to go on a wild goose chase learning about the US tungsten industry of 80 years ago, nor learn Russian. If you could cite some specific companies that'd be great. As I pointed out, most of Germany's tungsten came from Spain, which has tungsten deposits in abundance.
Should you have enough time in the future, I could share with you also my monograph (currently in draft) on the long history of the current conflict Russia is involved in. Thousands of archival documents, links to sources etc. And the document is being composed in English, so I hope there won't be any problems reading it.
