The floors do not appear to have been refinished maybe once since the
original installation. I removed a stair cap once and the edge of those
boards looked very thick. I guess I will not know for certain toil I pull
something up.

Do the old flooring boards need to be edge plained or process for good fit
during installation ?

Use a thin cut-off wheel in an angle grinder or die grinder to cut off the
nails where they come out the bottom, and cut off any large splinters down
there, too.
