of the mentioned in that post....
One of these Demag D7 (not an artillery piece, but mentioned few times), while with a Pak.38 or Flak30/38 can be an artillery one....
M101 (105mm) used from WW2 -Korea-Vietnam-Iraq and still in use with canadians (modified one - BTW can somebody provide me with details of Canadian mod's - drawings are very welcome).
Sincerely Alexey.
