Steve: Go to the National Archives in College Park Maryland and look at the records yourself if you doubt their "Proof." Sometimes "conventional wisdom" can be simply wrong.
Did you even read my last response? I noted that Nikon Inc., itself listed the 35mm f3.5 as coming out in March 1950 on the company's own web page. You are relying on fifty-year-old memories, not on documents. I am relying on documents, not on some company veteran recalling "Oh, yeah, we had the 35mm lens back then."
As for the 1947 fisheye lens, NK included a photograph of the lens in their booklet for the SCAP authorities. Neither NK or SCAP ever claimed that the lens was available or in production, just that the company had prototyped and was "capable" of making such a lens. That is not an "inaccurate" statement as you maintain. The booklet also included the Nikoflex, and we all know what happened to that camera.
A lot of false information went out about the early days of the Nikon camera. Some of that misinformation was deliberately sowed out by Ehrenreich to enhance his own reputation. The Oft-made Statement that SCAP banned the "Export" of the Nikon One is definitely false—as proved by research in contemporary publications, interviews with Liholm and Gasser and SCAP records, yet you have never gotten around to correcting that statement in your own web pages on the Nikon One.
What is possibly true is that the Nikon camera was not allowed to be sold through the CPO (military exchanges stores). But that is not the same "export."
To return to the 35mm f3.5 W-Nikkor. SCAP optical production records appear to have picked up and listed items when the various companies finished them and moved them to an availability-for-sale status. Which would mean that the 35mm Nikkor was not "Available" prior to April 1950. That does not mean that NK had not manufactured 35mm optics prior to 1950, it just means that a customer (whole-sale or retail) could not buy one.
NK manufactured a bunch of 80mm lenses for its Nikoflex, but they do not appear on SCAP records because NK never actually made the camera. They would have appeared on the Aires Camera entry when that camera appeared on the SCAP lists.
Please read through all my past entries on this topic. I am not relying on hazy memories, wishful thinkng or even just on optical production reports from SCAP, but a wide range of sources. When I first read the production reports, I was as surprised as you appear to be to find the 35mm lens not appearing until 1950, but then I went back and compared the records with all the other information I was gathering and what other contemporary writers was stating, and I had to reach the conclusion I have.
You may "wish" to believe that a person buying a Nikon in the fall of 1948 could buy a 35, or a 135 in addition to any normal that the camera came with, but it did not happen that way. NK planned to sell the 35mm lens, may have advertised it that way and even believed that would have that lens available "Real-soon-now," but it did not happen. Unless you, or Bob or someone else can show me a receipt for a delivered, production 35mm w-Nikkor dating prior to 1950, I will stick to my position.
