Hi there!
I have not been aboard for years but heard that you had some questions about the diffrent kind of ways to attach the skin to the innerstructure.

Most cars I have working with have a inner structure with just a lip who the skin is just wrapped around.

Some Italian cars from the 30s to 60s have another design at this detail.
They have a 90 degree bend all around the inner structure and also the skin have a 90 degree bend.
That means that the skin is just slight larger than the innerstructure and slide over it, then it is spotwelded together, no fold over or wrap is done.

Good or bad? Well... good is that IF the inner structure fits perfect in the opening the gap will be perfect too!
Bad is there are VERY limited chances to adjust the unit to fit perfect if the gap is a bit off.

At " normal" doors, hoods and so on it is pretty easy to adjust the gap with hammer and dolly work, both plus and minus if needed.

Hope you understand my way to try to explain.
