I knew Paul Miller when he was making cannons in his garage in Baltimore MD. Then he moved to Coolville, OH and expanded his business considerably.
If you ever met Paul, he had more enthusiasm for cannons than most anyone I've met. It was almost a childlike enthusiasm and fascination. His business reflected his enthusiasm. His products were his own designs in many cases, particularly when it came to carriages, generally resembling but not copying original drawings.
Paul had a knack for getting contracts to make numbers of duplicate cannons for wealthy collectors and organizations, such as one particular Native American tribe in the northeast. He told me their reservation shared a boarder with a state park, which had some cannons in it. The tribe wanted cannons big enough and numerous enough so they could clearly outgun the state park next door.
Paul was a Vietnam veteran and put considerable time and effort in to V-V causes.
RIP Paul and Susan.
