Did a bit of an internet search which I thought would be easy to identify this telephone box (type/date/original maker etc) and could only find one image other than the one I took and posted on "remember these all our yesterdays".Case number 1.
Can you dig out any information on this type of telephone box (type/date/original maker etc)
Added to that it just described it as a "sliding door telephone box" probably totally inaccurate it probably had a folding door of some description. Obviously my phone box didnt have the door in situ.
In the nostalgia for the tradition picture postcard box, has the memory of these more moderns been erased
