I've seen this type of bowl linked around the forum a few times, but I feel it needs it's own thread for ID purposes.
Perhaps Stolzle Hermanova Hut?
Measures 13cm across plus balls/bobbles x 5cm high. (99% sure it's Uranium, but son ran off with UV torch, so can't double check that at the moment).
If Christine and Angela would like to add pics of their variants, that would be great.
I notice all these bowls have the lovely little stubby feet I am so fond of, which appear to be the same as the ones on the Stolzle Hermanova Hut set of shell shaped dishes I uploaded earlier here:
