The Germans bought a lot of Star (and Astra) pistols from Spain during WWII and used them as substitute standard pistols.
When the allies landed in France in June of 1944, they cut off lines of communications with Spain. As a result, Star and Astra pistols that had been ordered and paid for could not be delivered...so they sat in Spain.
Fast forward to 1955 and the German's get political control back and the allied occupation ends... The German police were mostly armed with S&W 38/200 revolvers that had been lend leased to allies... Because the German police were not at all familiar with revolvers then were not happy with the guns and wanted replacements.
The Germans were able to arrange delivery of the Spanish guns they had paid for in 1944 so the police got some 9mm autos at almost no cost... The Astras were used for quite a while... while the Stars background is not well known. In Military service a lot of Stars were used by German allies during the war.
Ultimately the Star B guns came on the surplus market, most recently in the form of Star B pistols imported a year or so ago. The top grade guns were sold for $249 IIRC.
The Star is a decent gun derived from the 1911, but not identical by any means.
FWIW
