Centra Batteries Logo 1920s-1990s

David Podhorzer was my father born circa 1905 in Lwow killed by the Nazis shot outside his factory in circa 1942. I was born in Lwow in 1941 and by the time I was one end of 1942 both my parents had been killed during the war . From about 1925 until he was shot outside his Centra Battery Factory he owned and represented the originally German company for the whole of Poland. His factory was in the centre of Lwow and I visited  there around 1990 and it was still there but no longer a battery factory but  it had many army vehicles stationed there so I could not get inside as it clearly had become a military building of some kind. Can anyone share any more information about the factory in that period or later and any photographs of my father and the factory

 Can anyone assist with any photos or other information about my mother Dora Samet who married David Podhorzer in 1937 in Lwow Poland but was killed by the Nazis during World War 11 in about 1942. I was born in 1941. Her brother was a doctor a cardiologist who went under the name of Josef Maciej Sanecki and worked before the war and during part of the war in the Jewish Hospital in Lwow.
