Hi John -

I agree with Jim B. that there are different shades of black and with Jim
C. that it is unlikely you are dealing with lacquer.  However, that
doesn't mean you cannot use lacquer for your repair.  It is a very
convenient finish for repairs because of its quick drying and because it
"melts" into itself completely.  It also bites into other finishes quite
well.  

The final color and sheen depends to some degree on how much you rub out
the finish (to what sheen), and whether or not it is clear coated or not.
 I suggest you try finishing a few scrap pieces and try some without
clear top coats and some with, using a couple different black paints for
your color.  If the top coat of the original finish was a clear coat
(probably was), you can be assured it has darkened to amber a bit over
the years.  A similar "aged" color can be achieved with a dark shellac,
or a shellac colored with alcohol dyes.  Also remember that the finish is
a completely "filled" finish, meaning you will have to build up enough
material on the new wood to eliminate any grain telegraphing through. 
I'm sure if you "play around" in the shop for a couple hours you will
come up with something that is passable.  Before matching, make sure the
piece you're trying to match is good and clean and polished, to give you
a more accurate look at what you are aiming for.  

If you have any other concerns, feel free to ask.
