Dear Carnut:
ad 1. In my opinion, partly correct
ad 2. Phil Sheehan: No, isn't easy to find: Yes
ad 3. It was not built on a 115.5 inches Ford chassis of the time. But shortened to 104 inches, yes... So Fyreline's theory, a '56 T-Bird chassis has been used, comes up with a math problem: The '56 T-Bird-chassis' wheelbase measures 102 inches
ad 4. Due to my profession, it is sometimes necessary to investigate more closely. The first approach is not always the right one. That's why I like to set puzzles where I know from the start that there are several possible answers. In a discussion, it would be quite possible to get a result. However, that doesn't seem to be possible on this page.
Cadillac engine is correct!
Answer to: ...your original post you asked “Please identify this car for one point”. Fyreline answered that question correctly....
Yes, I admit a mistake here, as I assumed that a puzzle-car isn't identified with a simple attribution. On the other hand, I am happy about it, as I will point this out in future answers to puzzles in order to get rid of senseless cheap points.
Assumed that this is a community that is interested in cars, not just in worthless points that you put on your shirt without actually understanding the purpose of the game
I was in need to remove some of my puzzles, due to this common question-text “Please identify this car for one point”, I used for them. As you say in your statement, I have to add all the questions I am asking for, as soon as I start a new topic! Perfect! I will do so. Will take a little bit longer, to specify every new puzzle, will be less fun and quite a lot of additional work, but you will get a legally correct puzzle-text. It's only for pure pleasure.
In the future, too, I will take great care to only answer those questions that are correct and complete in the question text when puzzling others. No more!
So, now to the world championship point distribution, the real purpose of this puzzle.
No matter what is right or wrong,
...'fyreline' gets one point and
...'Carnut' gets one point
But you are welcome to look at the appendix to this puzzle. Whether right or wrong remains a mystery, as I do not want to and will not write any further comment
