Hi Sgbdr and thehairbarebunch,
Thanks for the links to those docs, and great picture of the MX, i really need to keep my eye open for one of those. I read that towards the end of the war 100,000 round were sent to Italy, so in theory there should be a one or two to find.
In reference to my initial question about the MH variant, i have just look at the documents linked to by Sgbdr and found the following. Thank you all who have replied. Best Weasel
The translated text is below,
Hollow-charge grenades The thin-walled projectile shell (1)
of the M-Gsch. X (see there) is provided with a zinc dome (8)
and a steel insert (9) and contains a nitropenta charge (2).
The cylindrical projectile pin (3) is provided with a choke-groove (4)
It contains in an igniter holder (11) an unknown bottom igniter (10),
the impact on the 15 mm detonator (6) in the detonator holder (7)
Ignition should initiate. The projectile was only tested.
The same setup was, also unsuccessful, also for 3 cm gun ammunition proposed
