My father was born in June 1904 and he died in 1978. I have a general idea of his early employment record but I have a gap between 1947-1963, when my siblings and I think that he continuously worked for a single company based in Cricklewood, North London. All his siblings are dead and neither I nor any of my siblings can recall the name of his employer. My father was skilled in moulded and extruded plastics and I am searching trade directories to see whether or not any such companies are listed as operating in that geographic area. I would like to identify a source that would positively identify his employer - national insurance/ tax records for example - however I have a feeling that the relevant authorities would either not have the records available or if they did would not be able to disclose their content until 100 years had elapsed since his death. Does anyone have experience of a similar problem and if so did they manage to find a solution? Brian Beanland
