Polish 7TP initial double turret carriage IBG-35071

Description

The first 7TP (7-ton Polish) models were produced with a two turret version armed with CKM Wz.30 machine guns, it soon became quite clear that the two turret version was obsolete and work began to replace them 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 had been upgraded to the 37 mm gun.
