When is a replica not a replica?

Watching a show on SBS about rebuilding the E type jag lightweight race car called "The car money cant buy" (ironic, because they sold them for a million pounds and the originals are worth 5 million pounds).

So back in the day, 1960's, they were going to build 16 lightweight aluminium bodied E types for racing. They set aside 16 chassis numbers, but only ended up building 12, so now they're building 4 brand new ones. They're being hand built to spec as they were way back when, even found the original press to press out the bonnets.

So now we have 4 brand new E types built in 2015 but to exacting standards of the day with period correct chassis numbers.
The organisers of the Goodwood say they wont permit them to race because they're replicas.

Another automotive guru says "Unquestionably they are NOT a replica".
So if a guy does up an XY Fairmont as a GT, that's a replica or tribute car, but apart from year of manufacture, are these E types a replica?

Me, I don't think so, they're just built a bit later, if they'd been built a year after the originals, would that make them a replica instead of 50 years later?
