Aluminum Cal 9mm Mag?

[LugerVern]

Could someone please post a clear picture of an original Cal 9mm magazine bottom? More than one example would be great!
Are there legitimate variations in the script?
Is there suppose to be a period after the Cal?
What kind of plating should be on the tube?
Has anyone ever counted the rings on the springs of these early 9mm magazines?
Is there anything unique about the magazine follower?
What type of wood was used?
Was a particular type of oil used, or were they left plain?
When were the last Cal 9mm magazines last made (1910)?
Were there replacements made at some time, say in the 20â??s for the American or European post war market?

I would like to see some pictures in the gallery that show a proper Cal 9mm magazine if someone would be so kind?

I am pretty irritated at all the fakery; there are non destructive tests that can be done to sort out most fakes, but first we need to sort out exactly what we are looking for.
Most of the answers to the above questions are found in books but rarely in one place.

Thanks

Vern
