Hello grapppa -
I wish I could answer your question. Unfortunately, except for the dimensional specifications provided in the Luger blueprints which John Sabato is offering, I have not seen any other quantitative criteria for determining authenticity.
The blueprint from John Sabato indicates that the thickness was specified as 2.5mm with no tolerance provided.
