Does anyone have any information about where I can find the specs for this gun. French manufacture, St Chamond, same company that made the French WW1 tanks. Seems Norway had a few of these 210mm guns as coastal defence guns. Probably purchased after 1893 when Norway began making coastal forts. Still in use when WW2 started. Only info I have is a range of 16000 meters.
Quite a few in use by the Germans in Norway. hem.fyristorg.com/robertm/norge/Norw_weapons.html hem.fyristorg.com/robertm/norge/images/Norsk_21cm_kanon_m.jpg">
Apart from that, there's nothing much about this weapon. Some went to Romania.
