Ok, I've checked several auction sites that have sold Martz baby lugers over the past several years, and, suprisingly, some of them have listed the production number (in an oval behind the trigger plate). The highest number I've come across so far is 206. So if anyone is aware of, or has, a number higher than this, I'd be interested in knowing what it is. Maybe we can find the answer to a question that seems to be unanswered...
