I started as a 21 year old 7/1/69. I was the youngest officer in a department of 40 sworn officers. They now have somewhere around 140 officers. Revolvers were mostly carried with the exception of one officer who carried a WWII vintage 1911 and another who carried a S&W 39-2. A couple of the older officers still carried 38/44 HD's. I thought at the time they were ugly and cumbersome. My department didn't issue weapons at that time, but the chief had a box full of old military surplus Victories and would let you borrow one until you could buy your own gun. I carried a Navy marked Victory for a couple of weeks until I could get a finance company to loan me the money for a new model 10. ($85.00) I wish I knew where all those old guns were now. After the mod. 10 came a variety of magnums until the department "gun nut" introduced me to the mod. 58 which I carried until we were issued mod. 66's.
The call boxes were there for the foot patrolmen but they no longer worked because we now had walkie-talkies that weighed about ten pounds. (for foot patrolmen only) I was there when the phone company took them down and sold them for scrap. I wish I had kept one now. It would have looked good hanging in my house with all my other junk. Same with the penny parking meters and motorized sirens. The gun safe at the station contained shotguns, rifles, and machine guns from the 20's and 30's. They left the department when the old chief retired in the mid 70's. He had been there 40 years. At the time I didn't want any of that "old stuff" but did manage to get a Ithaca riot gun from the early 60's complete with hand guard and bayonet lug. I liked it because it was newer than the other stuff. I still have it.
I've got a few police marked guns, but not as many as I could have had. Hindsight is 20/20. Those are some fine St' Louis marked guns.
