Nice old gal. Don't worry about the low number myth as there has never been an incident of a low number gun having proper headspace and modern ammo blowing up. Back when I was heavily into collecting R.F. Sedgley Springfields, I had a 270 WCF Mannlicher style carbine that had been hunted hard and had 2+ inches of throat erosion. The 270 has never been a pooper and this carbine carried the typical stippled front receiver ring (all markings gone). Almost surely a low # action as Sedgley bought them by the truck full. If the customer supplied the action, the arsenal markings were left in place. I have sold most of mine but still have a few deluxe models: the short action 22 Hornet, the 22-06, 6.5x55 and 400 Whelen.
