I was reading your post and although, I'm a little late in responding and you may have found the relevant departments to obtain your Grandad's Polish Army service records, thought I'd give you the address where I have obtained my Father's service records. ( Two Lots ) One from MOD stating his services with the British and the other service Records are from his actual Polish Army service records all written by regiment officers.....
POLISH SOLDIERS WHO SERVED IN BRITISH UNITS IN WW II The British Government records of Poles who served under British Command during WW II can be obtained from both address I've written below. You will be required to prove a family relationship to the individual that you are researching. If your Grandmother is still alive she can obtain all Grandad's army service records FREE of charge, if she's not, then you will have to pay for these records. In your Grandad's records it tells you which MEDALS he received.
From this address below, I received my Father's Army Records (ALL IN POLISH ) Siberia to England........tells me everything, conduct, postings, divisions, sickness, injuries, hospitalised etc, etc.
