I'm afraid I have to disagree with you, Mirof old chap! Gammage also issued his kit figures with rectangular bases cast integrally with the figures. For example, I have multiple examples of Gammage's Prussian Seven Years War cuirassiers. Some were kits with the pedestal bases, others have the rectangular base cast with the figure. Given that this collection may be old enough, I suspect that all of them are original Rose kit figures.
True, though, that John Eden uses the rectangular bases, too. I don't think he cast the old pedestal bases.
He casts copies of other makers' figures, too. Most are out of print, from makers who no longer exist, but he's now casting Puchala figures. Those are not out of print, but are currently cast and sold under license by Muertiz Miniaturen. That makes them pirated copies, essentially.
Prost!
