As I remember it in the early fiftys, dragnet was set in the streets of san francisco and ben alexzander was webbs partner. I well remember one episode where webb and ben were sitting at their desks and a package was delivered to webb. He wouldnt immediately open it as he knew it was a gun he had ordered. Ben was real curious and jack let him suffer for quite awhile. I am not real sure if the gun was a smith or colt now but it was a lightweight .38 special 4". Ben pulled out his 6" K38 and was whineing about how heavy and harder to pack his was and was wishing he had one like jacks! The early episodes I seen they drove about a 50 ford. It always started out with jack talking something like this is the streets of san francisco. I work here, I am a cop. I think it usualy showed them driving on the hilly streets with the bay below. Thats the way I recall it 60 years ago. Werent the later storys set in los angeles? I will google it.
