I've just picked up one of these, the same as Marcus' one, not the others. It's 22cm tall, 8cm at the base. Handle in line with the barrel shape, slightly wobbly top rim.
I'd say there are no mould lines at all.
Obviously, the handle is formed by cutting the hot glass and reforming the shape - much like some vases you see with holes through them. There are lines inside the handle which, to me at any rate, confirm this.
This is an exceptionally difficult and complex thing to do with hot glass!
