Yup. That gun is restored. Not original. Case colors look good on the top and bottom, but are not right at all on the sides. And, as dave said, the checkering was never fully pointed up on those guns. They were flat topped with the lines cut to about half that depth. And they were cut very crudely. And the finish was lacquer. It is not uncommon to see the lacquer chipping around the edges of the checkering on higher condition original examples. The finish was never that nice.
Here is a super original example that just sold on GB.
