Summer 1974, I had $350 burning a hole in my pocket from Air Force ROTC summer training. I walked into a Lodi, NJ gun shop, and there was a 67 No Dash, stainless sights and all. One pistol permit (NJ sucks) later I had parted with the majority of that $$ and was the proud owner.
So, on a spring 1975 flight home from VMI, a connection took me through DC and was too late to check baggage. I told the agent I had a gun in the bag and she said, "you're not supposed to joke about that"...and then big as life on the x-ray screen. My compadre - who later became quite an Air Force lawyer - started talking, the checker said "I thought he was joking" and they let us off - the pilot put the piece in cockpit, I got it back after we landed.
Later sold it but always regretted it...so last year, a very nice unfired mint condition no-dash popped up on GB. They'll bury that one with me....
