I should add that I raised the mast through the tower to near the top of
the tower using a long rope through a hole in the tower top plate using
a gin pole. I then secured the mast, attached the cable from the winch,
and raised it into position.

I've done exactly that on my tower.

If you use a hand winch, be sure to use one with a worm gear drive (like
the one I got from Harbor Freight Tools) or one with a positive brake,
otherwise you're asking for trouble if the mast weighs a bit. What
you're asking for would be for the winch to "backlash" and the mast to
start falling with the winch handle turning backwards so fast you
couldn't catch it, with imaginable consequences. 

Why one would want to use an electric winch at the top of the tower is
beyond me.
