Well, It Hardly Qualifies As A 'Replica', Then

[Rev. Rye]

To be fair, a replica doesn't need to actually have anywhere near the real functionality (HA!) of the genuine article, such as it is, or would have been.

A replica needs a genuine article to replicate.   Otherwise it is a prop.

According to the OED, a Replica is "An exact copy or model of something, especially one on a smaller scale." In this case, it would be a model, not a copy, but still falling under the definition of a replica as provided by the most authoritative dictionary of the English language out there.

Casual usage does trump formal usage in most cases, of course.

[Rev. Rye]

Casual usage does trump formal usage in most cases, of course.

And, of course, any dictionary worth its salt would account for both casual and formal usage, which is why it covers both "Exact copy" and "model."
