Hi Rahish,
I think that your best bet is to contact the Ministry of defence to obtain his service record. You can do this from the following link.
http://www.veterans-uk.info/service_rec ... rds.html#2This is an extract from their website as above.
Records of Deceased personnel
Enquirers must provide the consent of the Next of Kin and unless the person died in Service, proof of death. A charge may be made for enquiries. Prior to 1972 all Royal Navy personnel were given their service record when they were discharged. For pension purposes the Royal Navy retained pay details. Therefore the only data held on Royal Navy personnel who served prior to 1972 is their Service details (number, rank, name etc) and a list of dates and ships/shore bases.
Certificate of Kinship
Information from the personal record of a deceased Ex-serviceman/woman can be released only with the consent of the official Next of Kin. The form aims to identify whose consent is required and the data you provide will be used only in connection with your enquiry. The form is retained for 2 years should you have subsequent queries. To download the Certificate of Kinship form for the Army, please click here.
For the Royal Navy, please click here.
Where do I send my SAR form?
Personnel records are stored at archives and repositories throughout the UK. Additionally there are also Subject Access Request Co-ordinators for each Service. You must send the completed SAR form to the relevant address.
Sorry I cant be of any more help.
Regards
Ron
