Hi Mike,
I had a look at the link you posted, very good. Nice if every aircrew had something like that.
The army service records seem to have changed, there doesnt seem to be the need to be n-o-k anymore, not sure if its the same with RAF?
Sorry to sound like the voice of doom, but have you checked the CWGC site, just in case.
I'm sure someone else will be along shortly who can help more, I hope you are succesful.
Pete
