Splodgy glazed bowl - anyone recognize it?

I've not seen one quite like this before and it's not giving me any clues. Can you help identify it? Thank you!

Anyone?

Looks like a splatter glaze bowl from the 30s-50s, but I've no idea which pottery made it, or where it was made.

Thanks Naomi. It reminds me of that pottery that's often mostly brown with edges of splatter but I can't think who makes them either.
