The sleeve with the green/black Stresemann stripes is the result of numerous manufacturing steps. Firstly a small plate of
raw material is punched out of a sheet and then welded into a tube.
|
 |
Artificial resin is sprayed into the inside of the tube, sealing it to prevent the ink from leaking. |
 |
A high-precision lathe with grinding diamond then gives the Stresemann barrel its classic profile and leaves it smooth but
grippable to the touch.
|
 |
The cap rings are cut off a brass tube and then gold-plated with high-quality material. An injection moulding machine fixes
the rings to the cap.
