Polish 7TP initial double turret carriage IBG-35071

Description

The first models of 7TP (7 tons Polish) were produced with a version of two turrets armed with CKM Wz.30 machine gunsIt soon became quite clear that the two-turret version was obsolete and work began on replacing it with a single turret with the 37 mm gun.
When the invasion of Poland by the German army began, there were few 7TPs left that still had the two turrets, almost all of them had been upgraded to the 37 mm gun.
