The arm to this door spring was bent in a number of places and twisted, the spring itself was broken, the fixing flange had a corner broken off and all the hinge points were loose and tired.
I was surprised at how small the closer was, especially as I recall the doors to the old phone boxes were heavy cast iron affairs. I took the shot of a Briton A so you can get a comparative understanding of its size. While talking to the owner (Tony) of Unicorn Restorations I mentioned my surprise at how small the door spring was only to be informed that the doors to the old phone were wood, not cast iron and were therefore much lighter than I imagined and as it turns out wrongly recalled.
Here are some links to the history of this most British of icons and Unicorn Restorations for those wanting more information.
