Are you sure there are not more wires tucked inside the box?
Perhaps wires/box is partially covered with wall paint and/or plaster?
Are they bare all the way through the box and behind?
If the wires are completely bare then they are probably all ground wires. If
not then you have big trouble.
What was the purpose of the restoration? Were circuits added or was he
adding grounds to existing 2 wire circuits?
