All of my childhood lego, kenex and mechano which I have no use for, would be great for any child aged 4+ or any collectors out there.
There is only a small amount of mechano with one clockwork motor but is all in pretty good condition same goes for the kenex which also includes quite a few instruction sets with all the parts.

The lego was my pride and joy all of it comes with instructions and all of the peices for the sets, there is some really rare sets in there too which you would be hard pressed to find anywhere!
