From hints in the previous discussion, it seems that this pipe was
outside the
heated house, and it probably froze at some time, but didn't quite
burst.
I'd consider the whole length to be suspect, and replace it. Another
possibility
is to stretch the copper of a fitting (little hammer and the horn of
an anvil
will do it) until it fits, so you can solder a standard size fitting
and
connect up your new work to that fitting's unstretched ports.
