This is a DRC (Drag Race Specialities) Slot Car chassis.  I believe the scale is 1/24th, but it could be 1/32nd.  It is used and has some rust here and there.  The front wheel axle is bent.  The motor works ok, but it will need a cleaning and probably oil.  The chassis could use a cleaning.  See pictures / photos for more detail.  Buy multiple lots and save on shipping costs.
