My understanding is that there was only one supplier of tamahagane (玉鋼) during the 1930s and 1940s. How the production of this material was restarted can be found at the JSSUS website. Click on "Yasukuni-to PDF" in the upper right corner. By clicking this icon, a PDF download will start.

In addition, there is a thread on this forum that briefly mentions the Tatara Forge.
When Was Tamahagane Officially Required to be Concidered "Nihonto" or "Gendai"?/

It is likely that the army probably secured the entire output of this material and then supplied it to Yasukuni Shrine 日本刀鍛錬会 and the Rikugun Jumei Tōshō 陸軍受命刀匠.

It makes me wonder, if your suspicion is correct, why we wouldn't see the Star stamp on their blades as well?

Yes, I can't find it there anymore either. He must have deleted the page.

There looks to have been something of a revamp of the page, and a lot of information lost.

He used to have a good page on the Koa Isshin, and that is gone now too.

After reading the linked PDF, it seems the tatara 鑪 [furnace] was at Yasukuni. Now it is your turn to read the PDF.

You need to login to NMB to access downloads. I have directly attached the PDF for your edification.

I was able to view and download the webpage in question via the Wayback Machine. It was, as you inferred, a rather interesting read. I for one am glad that you have such a good memory!
