Early Push Button Wall Phone ?

Here we have an Old style Saisho 425 push button wall phone with a depth of only 75mm it is ideal where space is limited but it also looks fine just sitting on a flat surface. We had one of these in our kitchen 30 years ago and it still looks OK now.. This one has changed colour (not painted, just faded) over the years to an even light brown from the baige in the 2nd picture but it looks good, almost looks two tone when you lift the hand set. It iis sure to be a good talking point! Works fine on our sky phone line.
