I think it's the stem of the pipe that is unusual, tilting the pipe such that the bowl is horizontal. If a canted bowl is part of the zulu shape, I can't see that this is canted, just tipped forward by the unusual stem. Shapes are pretty squishy, so if you want to call it a zulu, it doesn't offend me, but to me this looks like a Dublin briar with an unusual bent stem that tilts it forward like it wants the tobacco to come spilling out. Jaunty, though. Albert had style.
