Many thanks for the input, everyone. I poured some water from the bottle and while it wasn't a particularly clean stream, it didn't dribble down the side; it still wouldn't suggest use as a carafe. I think the one thing that might discount it as a measure is the lack of capacity indication; I can't see a mark anywhere. It might well be an ink bottle but the neck interior is both wide and curved so it would need quite a large cork, perhaps disproportionate to the bottle's size. Additionally, the cut panels might suggest that it was intended as something 'better' than a simple utilitarian item. As for the yellow tinge being a possible indicator of age, I don't have the knowledge to say one way or the other but the heavy scuffing and scratches to the underside would seem consistent with a reasonable age. I think I'll just stick it in a corner of the dresser shelf as a mystery object!
