Scalextric track (Hoddesdon EN11)

Lots of Scalextric and similar car race track. 3 types, some genuine Scalextric, one unknown with lap counter and one that loops in air. All slight;y corroded, may need clean with steel wool or similar to get good electrical contact with car (use your own and PSU). The one I cleaned worked fine. take one or all. I estimate 26 pieces, could be more or less
