Yes, Dinklepip, :hi: they do, but their amber is a glowing rosy one, like the golden amber of WFs, Webb or Stuart.
(and yes, I know they're all different to each other, but they're all rosyglowing)
I can't see from the photograph of this bit what angles the top and base are to the stem, or how well constructed it is.
The stem itself looks a bit crudely done and the top rim looks simply polished flat.
I've got a Brancaster in my sticky mitts, and the top rim is both polished and bevelled.
The bowl of this bit has a thick base, with a thick sloping bit where it joins the walls, making for a more rounded, bird bathy shape at the bottom inside.
The base of this Brancaster is thinner, and the bowl is much wider and flatter at the bottom because the angle at the base and the walls is much sharper.
