There is a stainless speed six online with a different looking finish. It appears to be a matt finish, unlike the finish on my four stainless six series revolvers. I have read about the target grey finish Ruger offered on some revolvers but don't know which ones or how far back it was offered. Did any speed sixes have this finish? Maybe this gun was bead blasted later? Anyone have a picture of the target grey finish on any Ruger?
