Of course it was reconstructed, it was sitting in the ground for who knows how long.
Yes, I'll go there. I don't trust your word for it, and I'd like to see a source about that reconstruction done 2x, with the 2nd time to backwash Lucy to being an upright walker, because from my understanding when they found Lucy, they threw a party at the camp site because they immediately knew what the skeleton represented.
“they threw a party at the camp site because they immediately knew what the skeleton represented” this is 100% false. My source below will prove that.
Paleoanthropologist Donald Johanson of the Cleveland Museum of Natural History discovered and reconstructed Lucy with a normal ape pelvic. Later, Tim White RE-reconstructed it to resemble a human pelvis.
“Johanson recovered Lucy's left innominate bone and sacrum. Though the sacrum was remarkably well preserved, the innominate was distorted, leading to two different reconstructions. The first reconstruction had little iliac flare and virtually no anterior wrap, creating an ilium that greatly resembled that of an ape. However, this reconstruction proved to be faulty, as the superior pubic rami would not have been able to connect were the right ilium identical to the left. A later reconstruction by Tim White showed a broad iliac flare and a definite anterior wrap, indicating that Lucy had an unusually broad inner acetabular distance and unusually long superior pubic rami.”
Thanks for the link, but it doesn't really support your hypothesis, rather the opposite. The 2nd reconstruction was not done to distort reality, rather it was done to more accurately reflect it. It says the skeleton was distorted, which often happens with bones during the fossilization process.
Moreover, it makes the case that the knees of the skeleton are also indications that Lucy walked upright. I don't see any issues you have with the knees.
It proves my claim that Lucy’s first reconstructed pelvis looked like a normal apes. It was later reconstructed to look human.
The skeleton was “distorted” to appear like a normal ape’s pelvis. What are the chances?
Can you agree that both those things together can lead someone to be skeptical?
It claims that Lucy has “valgus knees.” So do female bonobo chimps. I address that in my post, however I am rather vague. I didn't want to overcrowd the infographic.
It was reconstructed wrongly, they say, based on them not noticing the distortion. According to your image, if it's correct, they didn't have the other half of the pelvis. Dinosaur bones were also put together wrong for various reasons, to include not fully understanding their anatomy compared to modern animals, for the same reasons as Lucy's skeleton.
I understand this leads to skepticism, a healthy dose of it. The theory of evolution has holes you could drive a truck though. But this reconstruction alone is not a nail in the coffin for me.
I'm not sure that bonobos having vagus knees matters unless it's claimed that bonobos aren't decedents from a common ancestor. Some primates down the line got vagus knees, like bonobos, and some didn't, like chimps.
The article you linked two notes it was not just the knees, it was the femoral head and the greater trochanter (which I had to look up, it's been years since I took anatomy) which is the bulge on the opposite of the femoral head, that leads them to conclude that Lucy walked upright. There there are apparently enough differences to show that Lucy walked upright.
The conclusion anthropology makes is that Lucy is the missing link. The brain size is tiny. Which means it's not. What they did find, was evidence of a humanoid that walked upright from about 3.2 million years ago.
Anyway, I try to remember it's (usually) a human being on the other end of any interaction.

No problem at all.

Do you know why the skeleton is named Lucy?

Just wanted to add, I am liking the civil back and forth.
