Many times Norm, we would send frames out for special treating and the regular frames would still be made and go out the door. The question was, what was the list gun MADE. The last R9 made was R6336. That is because that frame was sent out to a vendor for a special coating treatment which I kept to the side for a while. Once we were selling the company to Remington, I needed a gun for myself, so I made it out of the remaining frames and parts that I had at the shop, so R6336 is truly "The Last Rohrbaugh" made. Those high number guns that you have are truly some of the last sequential number frames to go out the door.
