I'd have to think it was sanded way below the original lines and re-checkered. Assuming the trigger plate is also proud of the wood on the bottom side, You couldn't just inlet the top and borrom tangs deeper without extensive re-engineering of the sears, safety and other parts. Damn shame people are so stupid. Other than making the stock too small, the checkering and finish look pretty good. I don't know any way to fix it other than restocking and that would be very expensive unless you can do it yourself.
