Hellcat
both, I believe, are the product of Craig Charleston's workshop, and I think both engines are from Vintage V-12's; don't quote me on this though. They are both "original" Bf-109E's, as built during the second world war, and both have combat history; the RG example I believe was flown at one point by none other than Hans Joachim Marseille, and was rebuilt from what was unearthed from a French beach. The FHC example I think came from Russia, but I'm going on memory here.
As far as "replica vs somewhat original" that would depend on your view of what defines each of those terms; I have the feeling that while both aircraft may contain a high percentage of Messerschmitt parts, how much is original to the werke numbers in question could be an interesting, and guaranteed eventually heated, conversation. Let's just rightly say that both are beautiful and extremely authentic examples of the breed that we warbird enthusiasts are very very lucky to be able to see, especially in their original liveries, and leave it at that.
Try here for some history on each:

Hope the "RG" get their example back flying soon, and I wouldn't want to be on the other end of Mr. Russel's legal team. Ever.

P.S. I'd love to see some "Buchons" in their original liveries, or at least in their original BOB movie paint. Especially the two seater that Connie Edwards has; see here:
