Many thanks Ivo. Much appreciated.

I have to agree about the shape, they are one crazy pair of vases - and I've never seen anything quite like them before either! I am sure they are really old as they have a fair old amount of wear on the base.
I don't think it would be possible to place three fingers in the aperture, as this only appears to be about 1" diameter, even if you could place your fingers down low enough to reach. I think they may have been each made in a different mould. The darker vase (pictured on the right earlier) has a less accentuated band around its 'waist', being more rounded than the other. In fact these bands are very different from one another. This darker vase also has a deeper concave base. I'm not too sure on what else I should be looking for, for evidence of different moulds being used. The crenellated tops seem to match.
Can it be roughly dated if as you say Ivo, it screams gothic revival? What period of time would that be? Would it tie in with the period in which the copper flashed technique was used in 1860s-1890s ? I quite like the idea of them being Gothic. They seem quite archetectural in design - rather like strange castle turrets, or even chess pieces.
