Is this large brown painted bowl Crown Lynn please?

This large bowl is 23.5 cm diameter and approx 6.8 cm deep. It looks like a three digit number has been stamped in the base.There is pencil writing on the base probably by the retailer with 17/6 being I guess 17 shillings and sixpence. It may not be that apparent from the photo but there are what I call “flute” cuttings at 6 cm spacing around the bowl circumference. It gives me the impression of the old painted Crown Lynn but I can’t pick it up from the gallery.

Hi, this cold painted decoration is not in the style done in NZ.
Most likely it is English, but I haven't found one the same shape yet.

I'm sure Crown Lynn did a 'fluted' float bowl, but I haven't located it and will go back and have another look when I get a chance.

“Cold” fits. It has a cold look and feel. Thanks Ev for the info.

Hi Ev. A further look in the sunlight and after a clean. There is a line diametrically opposed on each side of the bowl. The incised number at a guess looks like 437 or 427.

I can't get it to fit anywhere and think it's an import with that brown paint kitsch

Many thanks for your efforts Ev. I’m working through collection as you may have guessed by the number of posts. Hope this is OK. I’m learning heaps but I don’t want to guess and your information and confirmations are invaluable.
