Ehrfurt Lugers

I too think that you should look at the numbers carefully to ensure that they match and are period. The term "forced match" like "dip blue" is often mis-used IMO. A German Arsenal (like the "MA" lugers) or factory rebuild is hardly a forced match even though it may have re-numbered parts. These pistols were gaged and fitted as well as when first made...maybe better. It is well documented in Datig (I believe, maybe Kenyon...it's been about 30 years) that some WWI dated Lugers had the original dates ground (factory or arsenal?) and 1920 applied. As Johnny mentioned, check you Luger for Police features like sear and mag safteys. My guess if it is matching is it is a Weimar era authorized rework...in my book a very legit variation for a collection.
