I will probably be visiting the local history library tomorrow so will see what is available there. In the meantime you may wish to scan through the following online publication which was written by Sep Burgess who "ep Burgess, (Septimus) ( An actual seventh son of a seventh son) was born and bred in Ordsall, Salford in the heart of the docklands. Joined the Home Guard on its first day and after a very short time was promoted to lance corporal due to attending a crash weapons course at Altcar by the army. " Unfortunately it does not divulge any company details. sites.google.com/site/palsandneighbours/Home
I could not find anything giving section/battalion or coy information in the papers so I asked for anything that may have been in the archives. Due to a shortage of staff the lady had a quick look and returned with a box full of information on C battalion who were stationed at the town hall (zone 3). Here is a glimpse at the sort of info that may be archived.
I am not sure if C battalion (zone 3) covered as far as the Regent Road area. I did see mention of Cross Lane and some areas of Ordsall. I hope to investigate further when I go to the library next week.
