Dad's Sanctus Seraphin violin

Sanctus Seraphin violin that my father bought in the US in the 1940's and played for many years in Thailand, the US and Italy.
Dad bought this violin from an antique shop in Philadelphia while he was studying for his Masters at the University of Pennsylvania (1939-1943). His roommate there was Khun Chintamai Amatayakul. Mom said that it was one of the few possesions that the Japanese occupation did not sequester from him on his return to Thailand from the US during WW II with Khun Tuey Vutthikul, who graduated from MIT.
