Is it possible to retrieve from an overlay the parameters front-advance and

Without that it is not possible to make a new copy of an overlay AFAICS.

The source code of `copy-overlay' answers this question.

Thanks. Indeed it does ;-)  -- BTW copy-overlay is not mentioned in Info.


PS: The comment says "easily" because you can of course insert+remove a char
to check whether the position of the overlay's boundary stays "in front"
or not.
