Although not especially old this scene represents a time when there was a military barracks at Guildford. I recall parades such as these from my childhod.
I grew up in Guildford in the 1970's and 1980's. It was quite common to see the WRAC's at the railway station boarding trains crying because they had been posted to Ireland and of course in this period the situation in Ireland was a fragile one.
Whilst this picture and the story I have shared is not especially it old, it does record a time in the Guildford pictorial history.
