Soviet-Finnish War Diorama. Storming the Mannerheim Line. T-26 in action again with a T-26 OT flame-thrower version behind Barbed-wire entanglements were no defence against Soviet armour! The impregnable so-called Mannerheim line, 88 miles of fortifications on the Karelian Isthmus, was largely a myth of Soviet propaganda. I added a few wires to the flame-throwing tube and drilled out the end so it could be shown in action. The OT -26 or Flame thrower tank was based on the T-26 chassis. The Russians also called them ‘chemical tanks’ Химический танк ХТ-26 (ОТ-26) Now I know where the inspiration for the Daleks came from!
