In the summer of 1971 I was looking for an off duty weapon. I went to Potomac Arms in Alexandria, VA. Potomac Arms was the retail public outlet for InterArms. The store was practically empty, as it was a week day and summertime. A salesman was helping me look at various handguns when a large heavy-set man came over behind the counter. Yes, it was Mr. Cummings. I then spent about 2 hours touring the warehouse next door and seeing some of the most fascinating weapons I have ever seen. I also invested in a Colt Detective Special for my off duty weapon, at a very good price.
I only saw 1 warehouse, and never saw Mr. Cummings again, but he made an indelible impression. I did go back many time leaving portions of my pay check with Potomac Arms. Times were different then.
