Russell Hillsdon,s guns were made by the Birmingham firm, S.Wright and Sons. Wrights also made boxlock guns for H&H and Churchill. Prior to closing Wrights became subsidiary of Churchill. Having made several visits to the Wrights shop I can say that I never saw anything other than best quality work. Enjoy your gun.
For further info on the business connection between Russell Hillsdon and S.Wright and Sons, see the book,"The House of Churchill" by the late Don Masters, pages 281-2
