Welcome to the Forum. You don't need a 'membership' of xxx - they sound official but they aren't and I believe they only have basic information anyway so not worth the cost. You need to contact the MOD Glasgow for a copy of his Service Records. They are the ONLY official source of information. All you need is his full name and date of birth together with a copy of his death Certificate if he died in the last 30 years unless you are a Next of Kin. Search this site for details or a simple Google should find the details you need (apologies but I'm no good at posting links!). Finally don't assume he was 7th Armoured Division. Other Units are often described as such if they were in North Africa. Keep an open mind, get his Service Records and 'all will be revealed'. Good luck. Edit: I've just checked the MOD forms and you will need a copy of his Death Certificate.
