Little bit large for a rifle. Maybe a machine gun like a Spandau. Or small cannon or large calibre machine gun from aircraft fire would be that size, and would account for it being on the upper floors only.Big Al07 would know. He's an airshow enthusiast.
And a shooter of guns too! You can get surprisingly large holes in stone and brick even from the normal approx .30" caliber bullets used by most of the rifles of the time. The Russian army also has a very similar machinegun, a 12.5mm, to the Browning M2 fifty caliber that was also used in much the same way. Not knowing what city it is it is hard to say, but Warsaw certainly suffered much fighting, both in the early part of the war, as well as towards the end in 44/45. The Warsaw uprising was particularly hard fought by the Polish Resistance.
I never visited the Warsaw pact countries as a child, but did visit West Germany several times between 70 and 74, and although there were a few places where you could still see some signs of the war if you looked, there didn't seem to be much evidence. Much like in London, yes you can find odd places that still show signs of the blitz, mostly the visible stuff was gone by the early 70's. Usually the most obvious signs of the bombing would be a terrace with a house missing from the end, or even a gap. Personally only having been born in 64 I'm too young to remember too much about it.
I only remember looking for the signs of the war when we went on holiday touring europe by car, because even at that age I had an interest in aviation and old aircraft. My dad was a very keen RC aircraft modeler, and the flying club used the old perimeter track of RAF Hornchurch as the runway, and one of the E pen dispersals as a carpark. Add in a couple of pillboxes too, and it was a great place for a young kid to play. The last bit of the airfield near where we used to fly is now a "country park" and all signs of the airfield have now gone. They used the site for gravel extraction in the late 60's and early 70's, which destroyed almost everything, then built a housing estate on most of it. About 25 years ago there was I think a BBC archeology program called Two men in a trench, with the Scottish historian with the long hair. They dug old battlefield sites, and one place they dug was the country park bit that was RAF Hornchurch, looking for the E pen I played in as a kid! And here's a link to the program on Youtube.
