All Aircrew were issued with dog tags which they were supposed to wear, whether they did or not of course was another matter. The Dog tag would give, Rank, Name, number, and religion. The latter might not be the right one though as it would not be wise for a Jewish airman to bale out over Germany wearing something that identified them as being Jewish. I am not sure if there was any other information on them. I hope this is of some help
