Recently I was looking at a set of those grips, they fit my Model 38 RB perfectly. The one major difference was the medallion. The medallion in the "red, smooth" grips was very poorly cast, it looked blurry when held side by side with two other S&W grips. It was mentioned in passing that they were probably counterfeit from Taiwan or Thailand or even the Philippines. These seemed to be very open grained on the inside, more like mahogany than rose wood. The outside was filled and nicely finished but the medallion just did not stand up to close scrutiny.
