The Flicker gallery is not accessible without a password/sign in. The date stamp is not unique. There are many Lugers with what is erroneously called "double date". Actually your Erfurt was manufactured in 1917, but it was still in service after WWI during the Weimar era. The "1920" marking is actually a property marking applied to prevent government property from being sold commercially. You will see lots of Lugers and other firearms, usually those in police service, marked with this "1920" property stamp.
You will need to post photos here on this forum for us to help you identify the unit marking.
