Not factory. If it were a special edition, it would be noted on the gun with some sort of roll engraving. Even then I've never heard of any special attention being given to the lockwork. Mirror finsh blue or stainless? They did produce some models in a high gloss stainless but none in the SBH line. Some very early nickle plated SA's were also produced but again, not in the SBH model. Wooden caeses can come from anyplace and agin, if it were a special edition, the case would likely also bave some mention of is uniqueness etched onto it. Ruger currently offers a nice wooden/glass display case.
