WW2 Anderson shelter spanner. 1/2" Whitworth, rat-tailed. Unbranded example
£10
Each Anderson shelter was supplied with a 1/2" Whitworth "rat-tailed" spanner for construction. You used the end of the 9.5” long spanner to line up the holes in the tin sheets, poked the bolts through and then tightened them up with the jaws.
