Here is a slot car that made its way to me in a collection  of other slot cars , the vaccuform body is marked Cox , I know  they made these late 60's early 70's  , along with thimbledrome engines for planes , there is no damage to the body , breaks cracks etc , its survived really well , then the chassis which might be a kit or home made has a big motor in it , metal rails , a metal crown gear on the rear axel as well as metal drive gear off the motor  , the pick up pivots from the rear of the motor gear mounting plate, quite clever really ! Not tested it but there can't be too much to go wrong ! Find another one , please study the photos and email questions, signed for postage only.
