I have an old British postcard written 2 November 1944 from someone in Co. A 22th Bn APO 261. Card is stamped US Postal Services APO261. The details of the person (first name Harold) look like P.A.C.H. Kirw 32572831. He was writing to his sweetheart Miss Ruthie Baccher in New York. Can anyone tell me how I can confirm the details about Harold and where he might have been in the UK when the card was written please?
