Wait, wait wait! I want to hear that story.
Well, if you want to hear it, then it'll be your problem. (If you fall asleep during part of it, just go back and read it louder.)
A couple years back, I made a trip the the Benson Ford Research Center. This is located on the grounds of the "Henry Ford Museum", which used to be known as Greenfield Village.
I was interested in doing some research on the Ford Model S. For those who don't know, this is the car that actually cemented the foundation of the Ford Motor Co. with sales so good that it made it possible for them to push the Model T towards completion. This model of car (One real car group, but which comprised the Model N, Model R, and the Model S, were all similar, with the same chassis, transmissions, and engines, and only slight changes to the exterior features such as the fenders and running boards. (You can google them and read about them, they are quite interesting.)
I had a Model N-R-S frame, which was in poor shape, had been modified (to become a stationary wood saw, I believe) welded on, and was just generally pretty bedraggled.. I wanted to look at the original drawings, to see what was correct, what I could cut off or un-rivet as unnecessary, and what I would need to make the frame serviceable as a base for an actual restoration.
This is NO PROBLEM! The BFRC gives free access to all of the Ford archives. If it is in regards to your own project or restoration, you only pay for copies. If you want to get a drawing in order to produce a part, such as something for a Model A ("Yeah, no one is making the "magic frammis", so I think I'll go into production on it and supply all the Model A owners!), you can do that as well, but then you have to go through the Ford Licensing Office. They approve and control drawings used for reproduction parts. Understandably, they want to keep a close watch on products that bear the official FORD name.
The only requirement for the BFRC is to give them a few days notice, so they can pull the records you need to examine. When you get there, they have a box of records for your area of interest, sitting on a table for you, and you just go to it.
Ford records are basically of 2 types. There are paper cards that give information about any particular part, that is just written out. There are also micro-fiche records, that show the original drawings. There are no longer any original drawings from the early days of Ford. They transferred all the early drawings onto microfiche sheets, and the originals were then discarded. Also, some drawings have simply been lost. (Virtually everything from the Model T and Model A is intact and present, even the odd, unusual, experimental, and developmental drawings. But drawings from the earlier days are more of a problem.) (If you want to go there to see how they attached the headliner in your 1952 Ford Crown Victoria, those prints exist and are available, and you can go see them).
In any case, I requested the drawings for the Model N-R-S. (They are all in one group, and in one box)
The people who work at the BFRC are absolutely TOP NOTCH! I could not praise them more highly. There are a lot of ins and outs in the records, and they know some of the most obscure things you could want to know. The people there VERY helpful, and gave me a lot of assistance in finding the things I was looking for.
So now you have a box of little microfiche cards in front of you.
The first thing is that even though every Ford part has a number, that does NOT mean it is on just one drawings. There is a unique and individual drawing for EACH component that makes up that part. So when you look for a part drawing, you may actually be looking for 15 different drawings.
That is your first challenge.
The next challenge is that the old microfiche was photographed just as it existed. If the drawing was damaged, then it shows on the microfiche drawing. There is nothing you can do about that, except search through other drawings to see if there might be something that clarifies the area that is in doubt. This usually can be done, because there are also ASSEMBLY drawings, which show how each component was to be put together to make a completed part. At the time the fiche material was made, the old drawings were not that important. I am sure that no one back then ever thought that people would be arguing to the death over when a certain bracket was used in production, and which way the hardware attaching it was oriented.
Fortunately for me, one of the members of the Early Ford Registry, compiled a "Finder List" of drawings, so that if you are looking for the water pump, you can get in the range of the correct drawings, or, as in my case, the range of drawings that showed all the frame parts. I had a copy of his list, and I was GLAD that I had brought it along.
Many of the drawings are EXTREMELY difficult to read. I literally had to blow details up 20 times to get them to the point where I could make out what the actual dimension was. You are looking at VERY FAINT white lettering, on a completely black background. At times it was hard to even follow the outlines of the parts.
I spent a day there, and didn't even get all the frame drawings I needed. I got a lot of the info, but I will have to go back again, and the next time, I will be spending a week there, because a single day was too short, unless you are only interested in a single part. I spent $73.00 just for the day's copies that I needed.
So someone who is showing a Ford drawing, I GUARANTEE they have spent at least a couple of days, and you have to include the copy charges, (which aren't bad, but you need to copy everything that is important) the hotel stay, the gas, the trip to get there first, food, etc. etc. Doing research at the BFRC is NOT cheap. Someone who has uncovered an entire project, like the Henry Ford Sink engine, has probably spent $500 or more, just to get the info they needed to write the article, or come up with the designs. And on top of that, I think that the Ford Quadricycle and the Ford Kitchen Sink engine had either very few or no drawings at all. I know the drawings for the Ford Quadricycle project were done at the direction of the Ford Motor Company, when they wanted to build a replica, and this was in the 1950's at some time. Those were done by George D'Angelis, who worked in the Ford Engineering Dept. at the time. I have no idea at all how Mr. Ridenour got the drawings for the kitchen sink engine. I assume he asked for access, and actually took dimensions off the original kitchen sink engine in the museum.
