Hi there all, just acquired some information of my grand uncles occupation in 1942. Brinley Parker of Pontypridd, South Wales is , according to information I have, employed in 1942 in Northern Ireland. His rank or Profession is written down has (or should I say, looks like) Aircraftman in R.A.F. (1406664) (machinist). Does any of you good people know what this means, what the number stands for etc and possibly a R.A.F. location in Northern Ireland in 1942? Any help would be very much appreciated. Many Thanks
