20+ years ago, I was in Cape Canaveral on a business trip and I looked up the address for JAC, because I'd heard about the G19 conversion kit and I was interested in it. When I located the building, all it had on it was the address number and no other markings. I walked into the front door and into a small office lobby, and was greeted by a woman who asked if she could help me. I explained I was in the area and thought I'd stop by to see a Glock 19 conversion kit. She said, "Hold on a minute, I'll be right back."
When she returned, she brought Jonathan Arthur Ceiner with her. He had a Glock 19 conversion kit in his hand and he handed it to me. The slide was beautifully machined from solid aluminum and he offered to fit it to my Glock 19 right there as I waited. Only problem was I didn't bring it with me on this trip.
We chatted for several minutes. My impression of him was that he was kind of an odd guy.
I understand over the years he got grumpy and grumpier, and I heard reports of if a customer called to inquire about the status of their order he'd shuffle the customer's order to the back of the line. Complaints about his business built up and law enforcement got involved and he was charged with committing criminal offenses, which, IIRC, were eventually dropped, but I understand his business practices and criminal charges really affected his business.
