I discovered this box of Scalextrix track and accessories at the back of my mum's garage recently. Not sure if I have got the correct references for the track pieces but I have listed the items found below and which I hope is of help?
“The track sections do have rust and have been stored away for quite some time and the track does have rust and so will need some cleaning/attention. Two of the plastic barriers have a couple of clips which have split though they will still attach to the side of the track. The original printed cardboard Scalextrix Bridge is split to one corner and does show clear signs of wear.”
