Is model 1906 born in 1902?
 

A Luger in Springfield's museum, sn 10069B, GL markings, 9 mm caliber, was brought in Usa by Georg Luger in 1902. Commission Remarks (I don't have the text here) are: Modified extractor...ejector, firing pin spring and main spring improved... and so on.
The lock is of 1906 model. Not a modified 1903 one, but actually a 1906. Did someone look at that pistol? Did someone notice if the main spring is of a mod. 1906 type? In this case, the model 1906 was not designed by Dutchs, as Bas Martens reports in his book on Dutch Lugers.
Thanks to all for any news

R.A, The B suffix prototype range was completely independent of the normal DWM commerical serial number range, so I'd be surprised if 10069B was made as early as 1902. According to Kenyon page 90, Georg Luger's baby #10077B was probably made as late as 1905. TH

Thank you, Lugerdoc. The 10069B pistol has the GL. I believe the GL pistols were made before 1904. Maybe the Springfield museum's pistol is an assembly of many parts, but I did not look at it. A friend of mine has seen it in 1990 and reported to me the details. The pistol is reported as brought in Usa by Georg Luger, and of course this should be happened before 1905, as the following military tests were made on .45 Parabellum pistol. I don't have any further news

RA, According to my references the US .45 pistol tests were held in 1907 (see Kenyon p110 & p108 for info on another GL prototype #10158B). TH

Lugerdoc, don't rely on Kenyon. He was the first talking about Lugers ad has the merit to bring the attention on Parabellum pistols, but he's not fully reliable, as he did about Portuguese Lugers. After many years, in a new article he defines as variation a cut-away made in only three pieces. Kenyon, too, refers that swiss mod. 1900 lugers are 3000, serialized from 2000 to 5000!

I agree that Kenyon's info is a bit dated. Perhaps he or Still will give us some more up todate data on commericals and prototypes in their next publications. TH
