After posting, I found this on the internet:

I was at a gun show today in Iowa and a man there had on display, not for sale, revolvers and derringers made by an Erl Svendsen. I actually thought one gun box spelled it Svensen but the internet finds it as Svendsen. Anyway, I told the man I would do some searching because I like to do research. He had skimpy information that E. S. lived in Chicago area and made guns in the 1960s and maybe to 1970s. This man at the show had said he found 3 addresses somehow that ES had used in Illinois and he had met some man who had purported to know ES and knew that he had refused to pay off the mob or something so left Chicago. Then I found through a browser search an entry by Harley Nolden on the FIRINGLINE website from in the past because he had been asked about a derringer made by this ES or something. Harley had found a man who claimed he had known ES in the Chicago area on Rte 53 doing with a business named Hunter's Haven, I guess in the Chicago area. Apparently ES named his company eventually ESFAC, Inc. and they did make some derringers. I did also find an entry from Guns America that someone had one of these derringers for sale at some point in time for $130 but when I went to GA with the item number it was out of date and sold. Same thing with Gun Broker. So, who out there knows more about Erl Svendsen, gunmaker. I will tell you that his man today had a .22 SAA type revolver with a gorgeous condition cardboard box in which it came. The revolver was called a Pony Express I believe. The address for the company had no zip code and was dated 1957 apparently. (Zip code mentioned here as a way of dating things. Zip codes not used until about 1962-63.) Also, had two or three other revolvers with no boxes but I did not ask the caliber and I think a display box of like a set of three derringers. So, WHO KNOWS MORE??? This man is really wanting to know more and said he had Googled ES and found nothing. Obviously, he did something wrong as I found out something. If you know of any articles in Gun Digest or other periodicals or if you have a firearm made by ES or know any little tiny thing please post it.
