Long shot alert, help needed....I am trying to identify a London street from a photograph from the 1970's, and the only identifiable thing in the photo is a green junction box at the end of the road. I think the green boxes are for phone connections for that street, is that correct?
I notice they have numbering on the outside of the boxes, the one I'm concerned with has '25' on it. Most of the ones I recall seeing have only 2 digits, so is the numbering done for each borough or are they grouped together some other way? Does the numbering relate to the exact location/street name, and does anyone know what the numbering system is, or how I can find out? Or is it a secret code for BT employees only? In addition to the large number on the outside I also came across a sticker which has a serial number on it, which is 01744 could this serial number identify the street perhaps?
And final question, has the numbering system on the green boxes stayed the same for the last 40 years or so? So will a green junction box marked '25' in a particular area in the 1970's, be in the same place as one marked '25' today?
Bit of a random one I know, but hoping there's a BT employee or someone else in the know, anyone have any idea? I'd be grateful for any pointers, thanks
