1ST Btn Vickers Armstrong patch.badge

[arantxa]

This belonged to my Aunts husband Jack Foster he was at Vickers Armstrong Home guard he was 6ft 5 its immaculate probably because the patch was issued before the badge 9thery made them at the factory and he got it wrong and had it sewn on his hat ! Then he was issued another hat so it was never used My aunt gave it too me years ago and its been sitting in a drawer as im not really into Home guard stuff
Is their any way of getting Home guard records ? I have his medal and certificate
