Now it's you who is jumping to conclusions: In fact, I've checked my email correspondence —— and I found messages containing the search term «DKL». In fact, already years ago I had contact with a dealer of these adapters —— the answers he gave me were completely useless (and I was asking my questions in his native language!).
—— Now to start digging for an address of a manufacturer of the adapters in question (and they're basically always in China today?) and then to send them a comprehensible question: that would mean a time consuming but very probably fruitless task!
I am not jumping to conclusions, my answer to you is still the same as before, it is likely an error in engraving or silk screening the number.
The simplest explanation is always the best, Mr Occam rarely fails.
So what happened to your claim that these adapters are all from first class hoity toity British and German manufacturers? Now you say they are from China, well.. there you go, just low grade hit or miss Chinese ware that can have a manufacture's defect or two.

No such claim was ever imposed. To set the record straight:
[...] 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
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, e.g.:
—— eBay item number:223041521861
Brand: Cnscope
or
—— eBay item number:272544807844
Brand: FOTOMIX
Hmmmm... Different «Brand», different ebay store —— exactly the same text...

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.

Thank you! For some reason I couldn't find one when I searched ebay a while ago. Skopagon needs trying out!

If you enjoy your sophism, fine
No Sophism is involved here.
You asked a question and I gave you an answer.
You bringing up convoluted and laughable ideas that the numbers 4 and 9 are bad luck in Japan, therefor a Chinese maker of an obscure lens adapter decided to replace 9 with an 8 etc.
It is you who keeps arguing for the sake of arguing.

Dear retinax,
I presume that the Skopagon handles very fine with such an adapter, but according to the source I've mentioned above, apparently in some cases the adapter should be modified a litte bit. If you can read German, here's some additional info:

Fastest Deckel DKL Lens? —— f/1.9 OR f/1.8?
I'm wondering... I cannot find any information on a DKL or Deckel lens faster than f/1.9, viz. the fastest that I am aware of are:
Steinheil Quinon 1.9/50
Rodenstock Retina-Heligon 1.9/50
Schneider Retina-Xenon 1.9/50
Nevertheless, there are several adapters available having a fastest aperture f/1.8.
E.g.:
Can someone enlighten me, please?
I have a Deckel adapter from Fotodiox (Deckel to Fuji-X). It goes from f1.9-f22, but the numbers are not calibrated. In fact the adapter does not open my Xenon 50mm f1.9 all the way (they say I can cut the slot a little longer). It does work with my Curtagon 35mm f2.8 perfectly.
I think there were so many Deckel lenses made that there is no really universal standard.

I purchased one from China on eaby. It fits on my Practikas (LTL3 and MTL5) and my Fuji 605N, but the Pentax SP's have some interference (as does the Zeiss Icarex 35S TM PRO), and do not work. It does not work well with my Xenon 50mm f1.9 (aperture sticks sometimes), but is fine with my Curtagon 35mm f2.8. It is fairly inexpensive. Interestingly it is inscribed down to f1.8. My Xenon 50mm f1.9 has issues on both this adapter and my Fotodiox Deckel to Fuji-X adapter. I think they are rarer (f1.9s) and perhaps not well tested on adapters. The 50mm f1.9 Xenon seems to work fine on my Retina Reflex IV, but I have limited shooting on it (just finished a repair unrelated to the lens/shutter/mount- need to go and get).
