Well here are the pics of the one in question.

 

Yep, agree that says F253. I'm just wondering why the book doesn't list it for 1966, but could be a typo or omission. Not a biggie, just a curiosity and ND filled in the blank without batting an eye so he knows something that I'm not seeing in Ford print.

When you have an eye exam the standard chart will only use 19 letters out of 26. The seven eliminated are either too easy like I, or a detail to small like Q or Y, Or too complicated like M, A and W. The same almost holds true on computerized charts except they have unlimited combinations.

The letters used all have another letter that they are mistaken for and that is intentional. Separates the wheat from the chaff so to speak. S is commonly called B. A D is commonly called a O, C, G or Q. The same goes for all the round letters. An R for a P. A P for an F. A V for a Y. Given that you made the same common mistake of only seeing part of the letter and so came up with V.

As you can see there is a rational madness in using an eye chart and the scoring of your vision.
