Cable Reel. (Kennington OX1)

This has been in my shed for a few years so is quite dusty though I did unwind the whole cable and gave it a wipe.
I have plugged a lamp into all four sockets and they all work.
I haven't tested the thermal cut out so cannot vouch for this.
I am hoping someone with some electrical knowledge will know if this is ok to freegle due to not knowing if the cut out works.
