You mention you've requested his records from St. Louis. Occasionally, they find a record that's only partly destroyed. Not long ago, a client receieved a copy of a single, partly-burned document. This was all that remained of her subject's individual personnel file but it listed every assignment from his induction to his death. You might be equally fortunate. It'll be a while but let me know when - and what - you hear from NPRC. Then we'll go from there.
