The violin in the article supposedly made it through WWII.
They didn't go through anything like what Japan, Germany, or Russia did, with the cities razed by fighting (Stalingrad), fire-bombing (Tokyo or Dresden), or atomic bombs (Hiroshima & Nagasaki). If a French violin had survived the siege of Stalingrad - now that would be impressive. But just being in France? That's about as impressive as a random Englishman surviving the Battle of Britain.
