I live in Sheffield, South Yorkshire, England, and I too have found a National Registration Identity Card No: BCDP 157:2 for Abraham Van Lier of 89 Sherwood Avenue, Greenwood, Middlesex. It's signed and date stamped 22nd June 1943.
It was in amongst my grandad's Army documents and to my knowledge, we have no connection with the Van Lier family. Is it possible the gentleman is fictitious and the card was mass produced as an example of how Registration Card looks? Mine's in pristeen condition.
What's going on?!
