The black California Shelby American Manufacturer License Plate 013 with “1E” designation - 1E MFG 013 is produced as seen on the 1964 LeMans winner: the #5 Daytona Coupe CSX 2299.  The #5 Daytona not only won at LeMans in ’64, it also won the Tourist Trophy in ‘64 and both Sebring and Daytona in '65 (although not necessarily with the “1E” plate in every race.)
