The Ming Shi 'Unscrew 3000S' is available on AliExpress.
Perhaps the easiest way to find it is to search for -- faroot adjustable razor
Yes, not very promising, but neither is the product title -- Adjustable Double Edge Shaving Safety Razor Shaver Blades Zinc Alloy Chrome Hot New Razor Father's Day Gift For Dad
Nowhere on the product page is 'Ming Shi' or '3000S' mentioned, but an individual on a French shaving forum recently received one on February 7th and it appears to be it. Curiously, he didn't describe how it performed (yet). His photos show that the UPC for the razor is 6927002718129, but a search for that doesn't bring up anything.
Someone was selling them on eBay, but they're not currently listed. They were supposedly charging twice the AliExpress price.
You can also find it with a search for -- å士男士剃须刀手动刮胡刀新款旋开å¼å¯è°ƒèŠ‚锋利度刮胡刀架é…åŒé¢åˆ€ç‰‡å‰ƒé¡»åŒé¢åˆ€æž¶ -- and search on the page, though it probably won't be as easy to purchase from what appears to be an AliExpress competitor (for Chinese consumers). While this is found on Ming Shi's consumer page (aka Guangzhou Mingshi Shoudao Co., Ltd. or Guangzhou Mingshi Sword Co., Ltd, who don't appear to have a dedicated corporate website), they claim that Baume & Mercier (in the title of the product, but better known as a Swiss luxury watchmaker) 'has focused on the professional manufacturing and technological innovation of razors, and has taken the real needs of consumers as the research and development direction, which has driven the development of the entire razor industry.' Undoubtedly a different Baume & Mercier...
In any case, it's odd that Gillette still finds it profitable to make almost 20 safety razor blades worldwide, but doesn't find it worthwhile to reissue (and/or revise) their original safety razor designs. I'd think they'd be happy to have a customer no matter what product line they purchase.
