I believe this picture is of a 65 Shelby, 5S114 in Paris, France 1965.
As can be seen nothing of the stamp on the coil is visible.
I bought a stamped coil from Larsen and followed this picture when I
put it on the original engine in 5S275. Nothing of the stamp is seen and if
I remove the coil the print will probably be on the inside of the bracket.
