It might be one of the pairs on Ebay that come from Taiwan.
That's how I see it. While I have a feeling that the several who posted Taiwan called it right (unless they came from Thailand), my first reaction to those grips was that there was a very good chance they might be great grips. Checkering, THREE fingers? Only you can tell, by putting your hand around them, but you may have a nearly priceless set of grips. After all, a gun IS for shooting, isn't it? Isn't it?If you plan to use them, judge them on how they fit and feel in your hands. As far as quality is concerned, there's an old saying among horsemen, "There's no such thing as a bad color on a good horse."
Thailand. Bought off of Ebay.
