Got this 1/24 vac-bodied Revell Cobra a couple of weeks ago

It has the well known Cobra 427 body, sold by Revell in their line of 1/24 clear bodies, paired to a chassis

that seems a modification of the Lotus 23 Delrin chassis, with added mounting posts and for second series FT16D (can driven, big bearing) motor.
Besides having already seen some other example of this car, I know very little about it, so I will appreciate very much any information.
The car seems to me a late RTR model, made after the much more sophisticated asymmetric cars: may it be the last 1/24 car by Revell?. The chassis has "copyright 1966" engraved, but this may come from the original mould of the Lotus chassis. The car looks completely original to me. The decals are those coming with the clear bodies; there are no signs of a front decal on my car, and I remember seeing at least other two examples with the same strange placement of the three roundels. Does someone know if these cars came with the decals already applied? In the affirmative case did they come with a fourth roundel at the front? The original decal sheet had four roundels and I have a spare at hand, so I should be able to add a fourth roundel if this is correct thing. Also, were these cars sold in boxes or -more likely- in clear blisters as some late Lotus 23?
Many thanks in advance,
Eduardo
P.S. I forgot to say that I like very much that car. The older I get, the more I appreciate the slot cars by their character, general lines and stance. and less by the details, but of course this is personal.
