Special Constables WW1 Glasgow equipment, clothing, and role

[Ulsinus]

My great grand father was a special constable for Glasgow Corporation during WW1.

I have inherited his lapel badge, and long service award medal as well as a truncheon.

Using these 'bones' as a spring board I hope to flesh out the story of his time.

I contacted The Mitchell Library, Glasgow and the archivist confirmed that the library did not hold any records of special constables. They referred me to the Glasgow Police Museum. 

I wonder if any forum members have any knowledge they could share with me regarding the:

• clothing they would wear while on duty;
• type of equipment they were issued with;
• published guidelines issued to special constables to be followed as they carried-out their role;
• difficulties special constables would face as they carried out their duties.

Try as I might I haven't been able to unearth much information. 

This publication gives an overview but it focuses on England — The home front in the Great War : aspects of the conflict 1914-1918 by Bilton, David.

Grateful for the help, guidance, and suggestions of forum members of how I might answer these questions and other sources that I that might find useful.

Thanking you all in anticipation.
