What I glean from the article is that Gebrüder Merkel languished on the O/U effort until 1905 when they were able to devise a modular method or similar to efficiently and effectively produce stacked hunting gun platforms, as well as filed patents. But production for the War effort delayed their endeavors as well as the following economic downturn post WWI. But they still designed and patented their novel ideas for stacked hunting gun platforms. Then their wares started winning competition and that thrust them to the forefront.
