Drew, thank you so much. I assumed you would have answers. This gun is clearly a first pattern R grade marked "RES"inside and Marked Baker Gun Co. on the lock plates. It has to be in the first year or two of production. I was attracted because Bakers are predominantly Damascus, extractor and double trigger. My only other non- Damascus Baker is a Deluxe, circa 1920. When I receive the gun, I will report on my observations.
