SOME BACKGROUND ON THE 1906 GERMAN ARMY TEST:
Costanzo(1977, page 177, corrected page 248 06-05-2005)) reports 50 Army proofed 1906 Model Lugers were tested by the Imperial German Army. Walter (1986, page 131) reports that approximately 375 9mm caliber 1906 style Lugers were tested by experimental infantry machine gun detachments starting in 1907.
Surviving examples are described as follows. Test Proof and acceptance stamps on left receiver. 9mm 4 inch barrel. Flat toggle face without toggle lock, coil mainspring, new extractor chamber indicator, originally manufactured with “GESICHERT”(Safe) in the lower position, some later had the grip safety removed and were converted to the P08 safety configuration; the lower “GESICHERT” was knurled out and the “GESICHERT” was moved to the top of the safety recess.
To date, 12 1906 Army Test Lugers are reported in the 3-193 serial range. Of these 5 are unit marked, all to Infantry Regiment Machine Gun Companies. Which, lends credibility to Walters report that these lugers went to machine gun detachments.
Few of these 1906 German Army Test Lugers are reported in collections. The low serial number and alteration of the safety configuration to the P08 style on some of these Lugers, has lead some collectors to speculate that the first 1908 P08's were manufactured using safety altered 1906 frames. As the DWM-German Army contract called for new Lugers, the use of altered 1906 frames in the original German Army contract is highly unlikely. Some of these 1906 German Test Lugers that have their safety altered to the P08 style, may be in collections misidentified as early1908 First Issue Lugers.
