Hi, I picked these up in the usual hunting ground, a charity shop. I have seen on here that they could be called grapefruit or sundae dishes but these seem small for grapefruit. They are 2 inches in height and have 10 segments (maybe a grapefruit connection there

) in the lower half of the bowl with straight sides and a dark green foot. Its a set of 4. This might be a stupid question but for future reference, whats the difference between the two ? Im still looking for a maker so any help would be appreciated. Thanks
