what year, and I think it is one year only, E-Types had a small rectangular
chrome jag cat badge on each side of the bonnet, down low just behind the front wheels ???

 

If you don't get an answer you can look at the JCNA concourse judging guides by googling...

JCNA concours e-type

If any of them did come from the factory that way it will be called out in those guides. I'd start with the Series III as that kind of badge feels really 70s.

Good luck,

Jim

 

That emblem was on the late S2 4.2 cars (1971 MY).
Pasted from the Jcna S2 Judge Document:

Note: Leaping cat emblem used on some
late Variation 3 cars on rear
of bonnet wings - cat faces
forward
See references A, pages 140 (137) for picture.
Note: Chrome trim around front air intake (mouth) used on some
late Variation 3 cars
See references A,
pages 140 (138) for picture
Note: The above
models should have a 2R chassis prefix
and were made before November 1970 for
certification for sale in the U.S. in 1971
See reference G, page 7 & 44
