Does anybody have a manual, drawings or good photos of the 8mm cartridges for the Sander line thrower?
The cartridges do look like rimmed revolver cartridges with rose crimp (what is suspected to be the pre 1945 version).
The post war cartridges were turned brass and had an open case mouth closed with red laquer (with shot shell primer).
There is a low quality image on the web but not very helpfull.
Also the hs and the packing would be interesting to see.
