The story involves around a reunion of Home Guards. The Home Guard was stood down in 1944. While its members were slowed to keep some of their uniform, their rifle and ammunition would have been handed back in. There is no way in 1953 these former guards would still have their rifles to parade with.
The Home Guard were only entitled to the defence medal. They would not receive the 1939-45 Star or British War Medal.
While there were Home Guard bomb disposal companies, these were attached to large factories and made up of factory employees. They were also affiliated to the Royal Engineers. The Kembleford platoon would not have been involved in bomb disposal.
The Home Guard officer is wearing a fusilier cap badge. The platoon would have been affiliated to the Gloucester Regiment so he should be wearing their cap badge.
In the opening scene Mrs Devine's late husband is wearing the uniform and equipment of a regular soldier. Home Guards were not issued undershirts and had their own unique webbing equipment.
