This series of photos showing the manufacture of an award isn't actually 3rd Reich, but Japanese. The procedure is pretty universal however and gives an good basic overview of how the awards were produced. The first shows the pattern maker hand cutting the large (usually at least x4, often x10 ) master of the award which will by scaled down on a pantograph milling machine to actual size in the die insert. Traditional methods here, none of your laser cut dies used today.

The second photo shows the store rooom for these hand cut master patterns ( I suspect at the Osaka Mint)

Here, the award components are being stamped out. Modern presses are often hydraulic as the one shown here. The pressure required of course will vary dependant on the metal. Going by its size this one looks like a 20 / 25 ton press.

Note the die inserts with the shape of the award are cut into circular steel steel. This is then hardened and when in use fits into a recess in a normal mild steel die block.

The second example shown is a 25 ton press but with the pressure produced by a large flywheel on the side of the machine rather than by hydraulics, in the 30s/40s, most presses were flywheel types.

    • Brian: First, let me say that I always enjoy reading your blog and your "spot on" comments.  Another fine topic with such a broad expansion into so many different facets.  I had watched this a week or two ago and when reading your blog, it reminded me of this great quote.   There is a great video on the origins of "Who was Murphy in Murphy's Law"   Anyway, about mid way through this video, there is this great quote and I think it sums it up quite well to your statem
