One of my gunshow finds yesterday was a 38 HE with a 6" barrel.It is a RB with an extra leaf spring pinned to the front of the frame. All matching SN. everywhere there supposed to be,668XX.Large logo on the side plate and pat. dates on top of the barrel.Now on the side of the barrel it is stamped: S&W 38 MIL. The book says it should be stamped with something else. Does anyone know what might be going on here? Thanks, Jeff
