Is this Ramekin Crown Lynn?

for identification, possibly Crown Lynn?







vitrified I would say

This Stacking Bowl with ears is a good candidate, Shape 7617 in the Bristile range made c1984.

See how the measurements compare ... 65mmh x 150mmw including the ears.

height is 52 mm 120 mm wide including ears

I note that most Crown Lynn does have a full circle base rim
it is unusual in that there are 3 ridges in the base ring
I have seen this once before on a cup
with with the same rounded base and 3 ridges
It was a Temuka cup in an unusual shape
and in Temuka cobblestone glaze

So perhaps Temuka is a possibility if Crown Lynn does not fit
