This might be a bit off topic but for those knowledgeable about the military historian Janusz Piekalkiewicz I’ve a question on behalf of a private researcher. Would anyone know what happened to the WW2 photo archive of Janusz Piekalkiewicz? His aerial photos, ordnance survey maps and other maps were obtained by a Michael Foedrowitz but he doesn’t have the photographic archive, it was apparently sold to several people (?). Does anyone know what happened to it?
