No such claim was ever imposed. To set the record straight:
The first part after since —— «third party adapters that I happen to know are either British or German, from reputable makers with a real address» —— was an ...hmmm...? «blanket statement» —— I hope that makes sense, or is it an evil mirror translation?; yes, I failed to explain that this did not include DKL adapters. I do have many adapters, e.g. Periflex, and Novoflex, for many purposes, but I do not have any British or German DKL adapter (if they exist, they're made from unobtanium, I suppose!). Hence the second part —— «not from no-name makers in China that have just some ebay-store» —— now I was actually talking about the DKL adapters that are available (brass, copper, aluminium, whatever).
Sure you did make that claim, here it is at #8

Dear Brett,
You're correct, perhaps I'm a spoiled brat since the third party adapters that I happen to know are either British or German, from reputable makers with a real address, not from no-name makers in China that have just some ebay-store

That's true of course —— they have their limits, but these 60 years old Deckel lenses had and still have the benefit of great compactness, let alone compared to the most recent f/1.8 monstrosities for digital cameras

If you’re having trouble finding lenses faster than f/1.9 it’s because few (if any) production types actually exist.
It is right there in this paragraph that you wrote:
"You're correct, perhaps I'm a spoiled brat since the third party adapters that I happen to know are either British or German, from reputable makers with a real address, not from no-name makers in China that have just some ebay-store."
You keep contradicting your self.
Again, my answer to your original query is that it is likely an engraving mistake by the manufacturer, end of story.
