Saul Eig was not a gun maker, he was an importer (to the US) of inexpensive firearms made in several countries. Many were from Italy. An examination of the gun in question may show government proofmarks from the nation where it was made.
While EIG was mainly an importer of cheap Italian guns, they also imported a number of Japanese made Miroku .38 special revolvers in the 1950s and 60s. These guns were marketed to the Japanese police forces, who decided to buy S&Ws instead, and so the guns were largely exported to the US. Miroku is a quality maker, who currently make guns for Winchester, Browning, and others, and their revolvers, while not quite as good as Colts and S&Ws, are superior to guns from Charter Arms, Taurus, and many other makers. AFAIK, the only German gun EIG imported was a Rohm blank pistol that they modified into a cartridge firing gun.
The area of Eibar Spain was home to a host of small gun makers. That is also where yours was proof tested. It was imported by EIG of Florida (owned by Saul Eig) They are generally well made utility grade guns of modest value. If you remove the barrels, on the flat of the underside (known as the water table) there may be markings that indicate the maker. The numbers are the metric designation of choke diameter (I THINK full and modified choke) EIG has been gone for some time, with little information on the variety of guns they imported.
