There are a total of two almost complete shelters and the remaining sections of at least two more!
We found the original makers marks still painted on the interior of one of the shelters and I even got to check if my Grandad’s Anderson Shelter spanner fitted the original bolts (which it did!)
I was also shown a post-war .303 bandoleer ammunition box that was used to store tools.
Overall a very good day. I’m looking into working with the two groups to record the shelters and look in further detail at the construction methods employed.
