Well I seems I got my phones mixed up, I guess its an age thing
Seems I didn't get my 4800 untill late 89 early 1990 and my first one was in fact a Motorala 5000X and how do I know? I just found it with the paper work in the loft
I remember I wore the lettering off the numbers on the 4800 this has virtually no wear so I didn't use it for very long!
Commisioned October 25th 1988
The Useful numbers in the back are all mine so it was my phone (serial numbers match as well)
Mystery is How did I end up keeping it these things were valuable back then.
I'm Guessing when I changed my car the 4800X was already installed and there was no one to hand the old phone back to
So for the moment unless I find even more phones and paperwork that's my first one!
Cheers
