Tea chest - ply wood (Maidenhead SL6)

I know this sounds daft but I wonder if anyone collects tea chests. The wood is ply wood and the metal sides are a bit rusted now. Mind, I have had it as a shelf for the last 36 years ... Cannot remember why I got it but I know it was already old when I started using it.

Feel it is a piece of history and so am reluctant to just chop it up and chuck it.
