Haenel Magazine 16/20 round

[sheepherder]

OK, under Chapter 22 - Dead Ends and Curiosa, first page there is a patent drawing of a Simson extended magazine, but it is quite different than the one being addressed by the OP. The Simson extended mag has a telescoping jacket and follower. It states it was originally designed for the MP18.

Under 'Swiss Prototype Stocks', chapter 19 - Accessories, are shown several [small] pics of the Swiss 16-shot extended magazines, which look like long P08 magazines, no jacket or special checkering.

IIRC the 'Green' was first, Red second. And only the 'Red' was approved by the authors, too much editing/liberty taken with the 'Green' edition.

Edit: Norm was kind enough to explain the differences in thread -

Dr Sturgess took violent objection to the editing and a law suit ensued (Joachim Görtz died before the book came out). The "Red Edition" is dated 2011 and is titled "The Borchardt and Luger Automatic Pistols" and was published by Brad Simpson. Dr. Sturgess appears to be satisfied with this edition because he hasn't, to my knowledge, sued the publisher.

Pic of both attached. Different titles as well as different colors.

BTW: If you want to see what Mauser finally came up with to compete against the Luger in the 1907 Trials, search for 'second pattern Mauser 06/08 pistols' (on pg 1500 of the Red DVD)...That is one very pretty Luger look-alike!
