It's not my area, but I've never seen a Greener with sideplates like that, and I can't recall ever seeing a British gun with checkering like that. From that standpoint, it looks more like a graded American gun from the same period. If I stumbled across it in the shop, my first blush assessment would be that I was looking not at a fake, but at an unusual "target gun" of the era ... a Greener special ordered by an American or perhaps built for that market. The gun's configuration and the pigeon engraved on the rib make me think it was intended for shooting live flyers rather than for field use. And I might be dead wrong.
