U.S. Court of China

I am looking for a case form the U.S. Court of China. I am not sure if these records survived the war, or if this would have merited permanent retention. The case was a divorce case, Cause No. 4216, Case No. 2095, Tatiana Ivan Petroff v Alexey D. Petroff, from 1937. The court published a notice of the intended divorce in the China Weekly Review in 1927. A scan of the notice can be found here.
