Related: Polish Passports Pre WWII from the London Polish Embassy in 1935My Great-grandmother got a passport from the London Polish Embassy in 1935. Where do they keep records of this issued passport? I have only the passport number.
Try to contact polish home office "Ministerstwo Spraw Wewnętrznych". Try that first. Good luck!
