For those of us who shoot the old Chjarles Daly (Miroku) trap guns, I have found a great gunsmith that has an abundance of the old leaf springs and parts to repair the Charles Daly Guns. I shipped my gun to him on 16 December and it was back in my house on 30 December with all the springs replaced.
The gunsmith is: Bob Storms
2288 Barranca Drive
Lake Havasu, AZ 86403
Good work, fast turnaround and reasonable prices.
