Boring pressed glass fruit/dessert bowls but with a little something more

Hi
 
These little bowls are about 10 cm across and 6 cm tall and look despite some design effort pretty boring however, the base is irregular. This following down of the form into having more glass on oneside than the other is intentional and I felt just raises them above the normal run of the mill.
 

Ravenhead. Not sure of the pattern but might be Ice.

I had a look into this but all the Ravenhead have perfectly regular finish circle bases.

I have a large one, unfortunately packed away so I can't double check the base, but I'm pretty sure it's the same. This may be a variation on the pattern but I'd still say Ravenhead.

I'm with Naomi on this - Ravenhead

I can certainly see that they are in the same league with Ravenhead but the design just doesn't come up in any of my searches and without that there is no certainty

Pattern name is Topaz, design is often attributed to John Clappison.

You're the man Davee! It took a while but the smaller bowls listed in a set are a dead ringer.  

Thanks, I try to please   I knew we would get there in the end!
