Re: Could have been a Carbon Steel Alloy
There is a grade of Carbon Steel Alloy Known as "Swedish Blue Steel".
Frequently used for leaf springs,such as the sear spring at the aft end of the Luger sear.It can be tempered,(drawn down) to a softer more ductile state and formed into the shapes necessary for magazines.
This would probably have been supplied from the rolling mill in the proper temper in large quanity orders as would be required for a magazine forming production line.
If someone were sufficiently interested an analysis could probably be performed,on an old worthless magazine, by any of a number of quanatative analysis labratories, for a "Sum of Cash". How much? I have not the faintest idea.
