This is not correct. If those coated lenses exist they must have been coated afterwards. The coating technology was productionised by Zeiss - whether it was perfected just before WW II - late thirties - or during it is not very important because they started to use it during the war and allowed Leitz to coat some of their special lenses also during the war. Leitz tried their own methods but the coatings were soft, thick and inferior. After the war all German patents became public property so the technology was available for anybody. All the best!
