As shown in the picture, the C&H grips are usually more fully checkered (those on it are S&Ws from the mid-1950s through the late 1960s), also there is normally some engraving on the frame indicating that C&H did the work. You can see that in the picture, and it may also be on yours from your picture. I don't know if that is always the case. Whatever it is, it will probably be a solid shooter and general utility gun, but it won't have any collectible value.
