Polish ISU-152s

Were the 152s used by the Poles post war war time refurbs or 152Ks

Looks like just wartime ISU-152s that was issued to them during WWII.

Couple photos I found (and some intel from Poland) they did add some stowage. Bin on the right side, rear of the casement … looks like the bigger one on the T-55 turret. Another box on the left front fender, looks about the size of a Brit 25 pounder ammo box. And a small tank on the right front fender. One photo of one on display has a wire cage around the head light but operational photos dont seem to show it. (museum’s artistic license? )
