Hal,
It is hard to find a website when one doesn't exist. Don Bower's phone number is (303) 343-9596.
Don's gunsmith name is Don Burgess and his phone number is (307) 721-4867. You might want to call Don Burgess first since Don Bower's hearing aid went out on him last week and he can't hear well on the phone.
If you can't get a hold of either of them e-mail me at ernie1@ourtownusa.net and I will try to answer your questions as good as possible.
Ernie
