It has some similarities with Harriet's bowl, though the mould is different there are some similarities in the modelling, it is hard to judge without having both side by side for comparison.
I am fairly certain this bowl is not Etling/ Choisy-le-Roi. Siegmar Geiselberger thinks it is likely to be British in origin and I tend to agree. Closest pieces I've found in terms of finish and feel are my Jobling small rose bowl and 2602 Bird bowl.
I was hoping the metal rim might prove to be a useful lead, It seems to have been on the bowl since new.I've had a few pieces with similar rims in the past, including a cupped Jobling Oyster shell bowl, but I am not so familiar with makers of these metal mounts so don't really know where to start.
I suspect this is going to remain a mystery until any catalogues or other literature comes to light.
